This page will contain discussion groups about skype, as they become available.SkypeSkype (IPA pronunciation: /skaɪp/, rhymes with type) is a proprietary peer-to-peer Internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA and competing against established open VoIP protocols like SIP or H.323. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. The system has a reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. Skype users can speak to other Skype users for free, call traditional telephone numbers for a fee (SkypeOut), receive calls from traditional phones for a fee (SkypeIn), and receive voicemail messages for a fee. In September 2005, in a deal generally criticised by many as overpriced [1], eBay acquired the company for $US 2.6 billion in cash and stock, plus an additional 1.5 billion in rewards if goals are met by 2008. [2] FeaturesThe basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. Conferences of up to five users are supported. SkypeOutSkypeOut is a paid feature of the Skype Internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world. Unlike international long-distance calls made from conventional telephones, which are traditionally rated according to the relative distance between countries, SkypeOut bills all calls according to the level of telecommunications liberalisation of the destination country, the volume of calls made from and to a given country, and access charges such as those to mobile (cell) phones. This rating method is used due to the fact that calls are rated the same regardless of place of origin. This way, a SkypeOut user will be billed the same for a call placed to a telephone number in London, whether the user is calling from his/her computer in London itself, or from a different country. The Global Rate which is the one used for many countries, including nearly all First World countries, is currently 1.7 euro cents per minute. Credit, which is necessary to use SkypeOut, is usually purchased via credit card, personal check or money order, or online services such as PayPal or Moneybookers. The current deposit is either €10 or €25, which automatically expires after 180 days of inactivity — a timer is reset after each successful SkypeOut connect. In European Union countries, Luxembourg VAT of 15% is added to the charge, which makes the actual prices closer to €0.02 per minute. SkypeInSkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Germany, Sweden, Estonia, Switzerland, Poland and Brazil. (Although France, Germany and Switzerland give SkypeIn numbers only to residents). Cost is €30 for a twelve-month subscription, or €10 for a three-month subscription. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates. Skype VoicemailSkype Voicemail was released on March 10, 2005. This service allows callers to leave voice-mail messages for Skype users who are not online, on another call or otherwise indisposed. This can be purchased separately and is automatically bundled in with SkypeIn. Skype ChatSkype supports group chat with an interface similar to IRC. Skype Video CallingSkype 2.0 has a Skype Video Calling feature which has been implemented to enable videoconferencing. This feature is only supported when running Windows XP. ReleasesSkype Version 1.2 for Windows was released in March 23, 2005. Its most significant new feature is the provision of centrally-stored contact lists so that a user's contact information is available from any computer that is connected to Skype (in other previous versions, contact information was stored on the local computer). On 2006-01-05, version 2.0.0.69 of Skype was released. Versions now exist for Microsoft Windows (Windows 2000, Windows XP and Windows CE (Pocket PC)), Mac OS X and GNU/Linux. The Linux version runs on FreeBSD through its Linux binary compatibility. TechnologyEach Skype user must have the Skype software running on his/her computer. This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary. The main difference between Skype and other VoIP clients is that it operates on a peer-to-peer model rather than the more traditional server-client model. The Skype user directory is entirely decentralised and distributed among the nodes in the network, which means the network can scale very easily to large sizes (currently just over forty million users) without a complex and costly centralised infrastructure. Skype also routes calls through other Skype peers on the network, which allows it to traverse Symmetric NATs and firewalls, unlike most other VoIP programs (The two most common VoIP protocols, SIP and H323 are usually UDP and point-to-point, making NAT traversal problematic; see article). This, however, puts an extra burden on those who connect to the Internet without NAT, as their computers and network bandwidth may be used to route the calls of other users. The selection of intermediary computers is fully automatic, with individual users having no option to disable such use of their resources. This fact is not clearly communicated, however, and seems to contradict the license agreement which would limit Skype's utilisation of the user's "processor and bandwidth [to the] purpose of facilitating the communication between [the user] and other Skype Software users" (section 4.1). The Skype code is closed source and the protocol is proprietary which has raised suspicion and drawn broad criticism from software developers and the VoIP user communities. The Skype client's application programming interface (API) exposes the network to software developers. The Skype API allows other programs to use the Skype network to get "white pages" information and manage calls. The Windows user interface was developed in Pascal using Delphi, while the Linux version is written in C++ with Qt and the Mac OS X version is written in Objective-C with Cocoa. [3] GIPS iLBC CODECiLBC (Internet Low Bit-rate Codec) is a free speech codec suitable for most voice communication over IP. The codec is designed for narrowband speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbit/s with an encoding length of 20 ms. The iLBC codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. Features
SecurityGeneralSince the Skype code is proprietary and closed source the security of the software cannot be readily established. When run on Microsoft Windows, Skype binds to three ports on the user's computer and directly manipulates Windows XP's built-in firewall to accommodate these network bindings. Skype's file transfer function does not contain any programmatic interfaces to antivirus products, but Skype claims to have tested its product against antivirus "Shield" products. If the EICAR test file is sent over Skype's file transfer service, every major antivirus product appears to catch the virus and halt its transmission or reception via Skype. Skype accesses the hard disk several times per minute. This can be verified either by observing the HDD's activity LED or by using a file access monitor such as Filemon. Although those accesses are small, extremely fast and safe in the short term, they can be extremely harmful in the long term. In particular the continuous access pattern does not allow the disk to enter sleep or idle modes while Skype is active, even when offline. This can severely reduce the lifespan of the HDD when Skype is running for a long time. Stronger HDD caching does not seem to improve the situation. Niklas Zennstrom, co-founder of Skype, has admitted that the current security model would not withstand open-source scrutiny:
This would seem to be an admission that Skype relies on security through obscurity. Confidentiality of DataSince a Skype connection may be routed through an intermediate peer, 256-bit AES encryption actively encodes the data stream of each call, or file transfer. Skype uses 1536-bit RSA (2048-bit RSA for customers who have purchased any "paid services" such as voicemail) to secure the pairwise negotiation of an AES symmetric session key over an untrusted channel. The proprietary session establishment protocol is efficient and prevents both man-in-the-middle and replay attacks. The Skype server certifies each user's public key at log in. Integrity/Authenticity of DataThe integrity of the data, i.e. data modified while traveling though peers, even if encrypted, is unknown and undocumented. The mechanism and implementation has been examined in Bernson's report - referenced below. Authenticity of user identitySkype provides an uncontrolled registration system for users: registration requires no proof of the identity of the user at all. This works two ways: you can use the system without revealing your identity to other users of the system, but on the other hand you have no guarantees that the person you communicate with is the one he says he is. The down side of this is that it is easy to use the identity of a trusted person and trick a user to reveal information or execute a program sent to him. Prank programIn September 2005 a prank program was launched online. This unauthorised patch allowed a Skype user to masquerade as another user. The technique was for the joker to put up an attractive profile with a girl’s name and picture, and put that profile into "Skype me" mode. Within minutes generally another user would invariably try calling/chatting. The patch running the whole time would then partner up another call to the first caller, and send messages from the first person to the second, and vice versa. This way both people thought they were talking to a middle user whose profile of course was entirely fake. The patch only supported text messaging. History
Skype business ecologyDistribution partnersSkype has partnered with online web properties including Tom.com, PcHomeOnline, Daum, Livedoor, Bebo and Onet and hardware manufacturers including Plantronics, Logitech, Motorola, VTech, RTX, Siemens and Linksys.

Some findings:
CriticismsAs of July 2005, the line quality varies from excellent (comparable to traditional telephony) to barely usable. The main drawbacks are:
These problems can be minimised by using the service when the network traffic on the Internet is minimal between the ingress and egress to the network. This is however sometimes impossible. The issues are common for all VoIP applications; in fact in restricted networks many of them don't work at all due to firewalls and NAT routers in large private networks from which users attempt to use Skype; while Skype, and other VoIP services are at least able to connect through properly configured third party relay hosts. There are open standards protocols such as SIP and STUN which do the same thing. A broader criticism leveled at Skype is over its use of a proprietary protocol, instead of an open standard like H.323 or SIP, making it impossible for other providers to interact with the Skype network. There are of course clear business and technical reasons for this, such as protecting the SkypeOut revenue stream. A design limitation of Skype is, if given access to an unrestricted network connection, Skype clients can become supernodes. These supernodes hold together the peer-peer network and provide data routing for those behind restrictive firewalls. Unfortunately, these supernodes can generate a significant amount of bandwidth—saturating a high speed, 100 Mbit/s connection is not unheard of. For this reason some network providers, such as universities, have banned Skype. User count and acceptance is often no indicator as to the quality of a service. There may be superior services available whose number of users look poor in comparison with Skype as Skype has been more successful in marketing its service than other pre-existing VoIP telephony services such as VocalTec (established in 1995). The number of users quoted as Skype users are taken from the number of people that have downloaded the software and not necessarily used the service to make voice calls. SkypeOut rates do not always keep up with the general downward trend in rates charged by conventional telephone companies. For example, in the United Kingdom, the trend is for companies to charge a fixed price per call, for example 3p to 6p for an inland call of unlimited or long duration. With SkypeOut, calls are still charged at a per-minute rate as opposed to a per-call rate, meaning that SkypeOut can be comparatively expensive for inland calls. The Linux community criticized Skype for not doing any further development for Linux due to the fact that the last release was in October, 2005. The only proof to counteract the criticism is that Skype fixed a Mandriva installation problem on January 6th, 2006. (Release # 1.2.0.21) Prohibitions and warningsLegal and other barriers have been erected by companies, government regulators, and school systems. Reasons given include perceived threats to an economic interest, to national or enterprise security, to system reliability. China 2005SkypeOut was recently blocked in some regions of mainland China (notably Shenzhen) by the operator China Telecom for undisclosed reasons, believed to relate to SkypeOut's ability to take lucrative international and long distance business away from the People's Republic of China's state controlled telecoms companies. France 2005In September 2005, the French Ministry of Research, acting on advice from the general secretariat of national defense, disapproved the use of Skype in public research and higher education; some services are interpreting this decision as an outright ban. The exact reasons for the decision were not given, but computer security professionals point out that:
As such, Skype is considered a security hazard for research networks, in which there may be significant intellectual property. Skype vs traditional phone companiesPhone companies have traditionally charged users a large amount, often proportional to the distance, for long distance calls. Skype, arguably the first major VoIP software, allowed people to talk over the Internet for free. This led to many home users with broadband capability to switch to Skype for placing their calls over the Internet. Skype being secure and encrypted end-to-end, has also attracted large corporations who are beginning to switch from their traditional phone companies for their internal calls. Phone companies were all of a sudden out of favor in the markets which patronized Skype.[citation needed] Compatible productsNetgear newly anounced a skype preloaded phone which does not have to be connected to a computer to use Skype; it uses a WiFi connection instead. It has been announced that Motorola will release a similar product (CN620 WiFi cell phone).

i-mate PDA2 also comes with a preinstalled Skype. In his late work Conjugal Love he describes, that a soul of a man and a soul of a woman are united by the marriage in heaven to become an angel. The aceton skyfon WM1185-T cell phone is also preinstalled with Skype. The Christian mystic Emanuel Swedenborg has a similar imagination. It has been announced that Motorola will release a similar product (CN620 WiFi cell phone). The Sufi mystic Jalal al-Din Muhammad Rumi wrote in his poem Masnavi:. Netgear newly anounced a skype preloaded phone which does not have to be connected to a computer to use Skype; it uses a WiFi connection instead. When the human body dies, a soul could become an angel.
Skype, arguably the first major VoIP software, allowed people to talk over the Internet for free. Citing Crowley, people have linked the term with the Genius of the Golden Dawn, the Augoeides of Iamblichus, the Atman of Hinduism, and the Daemon of the gnostics.Guardian Angel. Phone companies have traditionally charged users a large amount, often proportional to the distance, for long distance calls. Within the system of Thelema, the Holy Guardian Angel is representative of one’s truest divine nature. The exact reasons for the decision were not given, but computer security professionals point out that:. Examples of such devas are Indra, Mitra, Ashvins, Varuna, etc. In September 2005, the French Ministry of Research, acting on advice from the general secretariat of national defense, disapproved the use of Skype in public research and higher education; some services are interpreting this decision as an outright ban. Buddhism and Jainism also believe in the existance of such devas. SkypeOut was recently blocked in some regions of mainland China (notably Shenzhen) by the operator China Telecom for undisclosed reasons, believed to relate to SkypeOut's ability to take lucrative international and long distance business away from the People's Republic of China's state controlled telecoms companies. They grant material benefits to humans upon praying and sacrificing to them, though they don't carry the message of Ishvara to the humans as in Abrahamic religions (a category of such beings also exit, called "devaduta" or "duta"). Reasons given include perceived threats to an economic interest, to national or enterprise security, to system reliability. They are celestial beings with supernatural powers, but also weaknesses. Legal and other barriers have been erected by companies, government regulators, and school systems. The Devas may be better translated as angels or demigods. (Release # 1.2.0.21). Many Hindus now say that this is a poor practice, because the best word for God in Sanskrit is Ishvara (the Supreme Lord). The only proof to counteract the criticism is that Skype fixed a Mandriva installation problem on January 6th, 2006. In English, the Sanskrit word Deva is exclusively translated as "god", which certainly gives a polytheistic appearance to Hinduism. The Linux community criticized Skype for not doing any further development for Linux due to the fact that the last release was in October, 2005. Also, angel-like beings called Tennin and Tenshi appear in Japanese mythology. With SkypeOut, calls are still charged at a per-minute rate as opposed to a per-call rate, meaning that SkypeOut can be comparatively expensive for inland calls. In Zoroastrianism, the Amesha Spentas have often been regarded as angels, but this is not strictly correct since they don´t convey messages, but are rather emanations of Ahura Mazda ("Wise Lord", God); they appear in an abstract fashion in the religious thought of Zarathustra and then later (during the Achaemenid period of Zoroastrianism) became personalized, associated with an aspect of the divine creation (fire, plants, water...). For example, in the United Kingdom, the trend is for companies to charge a fixed price per call, for example 3p to 6p for an inland call of unlimited or long duration. Angels are also a part of New Age beliefs. SkypeOut rates do not always keep up with the general downward trend in rates charged by conventional telephone companies. Michael the archangel was Adam (the first man) when he was mortal, and Gabriel lived on the earth as Noah (the one who built the ark). The number of users quoted as Skype users are taken from the number of people that have downloaded the software and not necessarily used the service to make voice calls. Names of some known angels who appeared are Moroni, Nephi, Peter, James, John, John the Baptist. There may be superior services available whose number of users look poor in comparison with Skype as Skype has been more successful in marketing its service than other pre-existing VoIP telephony services such as VocalTec (established in 1995). Although Cowdery, Whitmer, and Harris all eventually became disaffected with Smith and left the church, none of them retracted their statement that they had seen and conversed with an angel of the Lord, and indeed, even defended their claim of angelic visitation to their deaths. User count and acceptance is often no indicator as to the quality of a service. People who claimed to have received a visit by an angel include Joseph Smith, Jr., Oliver Cowdery, David Whitmer, Martin Harris. For this reason some network providers, such as universities, have banned Skype. described his first angelic encounter thus (Joseph Smith History 1:31-33):. Unfortunately, these supernodes can generate a significant amount of bandwidth—saturating a high speed, 100 Mbit/s connection is not unheard of. Joseph Smith, Jr. These supernodes hold together the peer-peer network and provide data routing for those behind restrictive firewalls. According to the official doctrine of the Church of Jesus Christ of Latter-Day Saints, (Bible Dictionary entry on "Angels"):. A design limitation of Skype is, if given access to an unrestricted network connection, Skype clients can become supernodes. Joseph Smith, Jr., founder of the Latter Day Saint movement (Mormonism), and several of his associates, claimed that they were visited by angels on multiple occasions and for a variety of purposes in conjunction with the restoration of the gospel of Jesus. There are of course clear business and technical reasons for this, such as protecting the SkypeOut revenue stream. Humans do not turn into angels upon death, rather they are physically ressurected in body and soul and judged by God on judgement day (and that should they end up in Jannah (heaven), they are given perfect bodies). A broader criticism leveled at Skype is over its use of a proprietary protocol, instead of an open standard like H.323 or SIP, making it impossible for other providers to interact with the Skype network. Every human being is assigned two angels to scribe a record of all actions done by the individual throughout their life, which will be used in evidence for or against the person by Allah on the day of judgement. There are open standards protocols such as SIP and STUN which do the same thing. There are eight massive angels that support the Throne of God (Surat Al-Haaqqa, 69:17). The issues are common for all VoIP applications; in fact in restricted networks many of them don't work at all due to firewalls and NAT routers in large private networks from which users attempt to use Skype; while Skype, and other VoIP services are at least able to connect through properly configured third party relay hosts. The angels Nakir and Munkar are assigned to interrogate the dead before judgement day; and there are nineteen angels over-seeing the punishments of hell unflinchingly (Surat Al-Muddaththir, 74:30). This is however sometimes impossible. Other angels include Michael (Mikaeel) who discharges control of vegetation and rain, Sarafiel (Israfil) who will blow the trumpet on Yaum al Qiyamah (the day of resurrection), and Azrael (Izra'il), the angel of death. These problems can be minimised by using the service when the network traffic on the Internet is minimal between the ingress and egress to the network. The archangel Jibril is attributed with sending the message of Allah to all the Prophets (including the Psalms, Torah, Bible and Qur'an. The main drawbacks are:. Angels, unlike the fiery nature of jinn, are beings of goodness and cannot choose to disobey God, nor do they possess the ability to do evil. As of July 2005, the line quality varies from excellent (comparable to traditional telephony) to barely usable. He was one of the jinn..." (Surat Al-Kahf, 18:50). Some findings:. Scholars cite the following Quranic ayat (verse), "And when We said to the Angels; "Prostrate yourselves unto Adam." So they prostrated themselves except Iblis. They produced some demographic information reported by Mathaba.net and Skype Journal. According to the majority of Islamic scholars, angels are incapable of commiting sin, and therefore cannot fall from grace, excluding Iblis who chose to do evil because he had free-will and is not considered as a fallen angel, but a separate entity made of fire called jinn. SR Consulting surveyed 4 million Skype user profiles in October 2005. As such, angels do not eat, procreate or commit sin as humans do. Visit the WizzTones Website. They can take on human form, but only in appearance. By downloading WizzTones, Skype users may create customized ring tones and assign every individual on their Contacts list a distinct and different sound, giving Skype users the freedom to walk away from their computers but still be available to identify and take an important call, or avoid an unwanted one. Angels are described as being excessively beautiful and have different numbers of wings (for example, Gabriel is attributed as having six-hundred wings in his natural form). WizzTones provides Skype users a simple and convenient way to create, manage and use multiple ringtones for a compelling, personalized communication experience. They are completely devoted to the worship of God (Allah) and carry out certain functions on His command, such as recording every human being's actions, placing a soul in a newborn child, maintaining certain environmental conditions of the planet (such as nurturing vegetation and distributing the rain) and taking the soul at the time of death. WizzTonesis a new and easy-to-use software product that works in conjunction with Skype. In Islam, angels are benevolent beings created from light and do not possess free will. Skype Id's are automatically displayed on search results allowing enquirers to speak to the business directly off the web page or send an email enquiry to the business. Angels are thus the ministers of God, as well as the agents of revelation in Islam. Morgle provides searchable links to Skype user web sites, provides each entry with a spam free business enquiry form, and allows users to display product or company pictures with a searchable advertising message. The belief in angels is central to the religion of Islam, beginning with the belief that the Qur'an was dictated to the Prophet Muhammad by the chief of all angels, the archangel Jibril (Gabriel). Morgle is a comprehensive world wide online business directory for Skype users. Official doctrines of most Christian churches teach that the virtuous are resurrected in the end of times, having a physical body again, unlike angels (see Swedenborgianism for a church that does officially and systematically teach that people enter heaven immediately after death). HansaWorld 4.3 attempts to allow users the seamless integration of Skype with ERP and CRM in business. The statement of 1Cor 11:10 could be interpreted, as if male angels could be vulnerable to the female attractiveness of worshipping woman. Built on top of the Skype messaging platform, Festoon enables Skype users to securely conduct video calls in groups from 2 to 200 and share applications, spreadsheets, presentations, or photos with others on a call" (from official website). (Zechariah 5,9) could be interpreted, that there are also female angels. Festoon is a Skype add-on product for Windows computers (2000 or XP with Internet Explorer 5+) that "adds video and sharing to Skype. male and female. Skype has partnered with online web properties including Tom.com, PcHomeOnline, Daum, Livedoor, Bebo and Onet and hardware manufacturers including Plantronics, Logitech, Motorola, VTech, RTX, Siemens and Linksys. Flavius Josephus (Discourse to the Greeks concerning Hades, VI) teaches of ressurected men and woman, i.e. The patch only supported text messaging. The Bible does state that at the resurrection, people will be like the angels with regard to marriage and immortality (Luke 20:35-36), and teaches such a transformation for instance at 1Cor 15:51; it states that the saints (all believers) will judge angels (1 Cor 6:3). This way both people thought they were talking to a middle user whose profile of course was entirely fake. In many informal folk beliefs among Christians concerning the afterlife, the souls of the virtuous dead ascend into Heaven to be converted into angels. The patch running the whole time would then partner up another call to the first caller, and send messages from the first person to the second, and vice versa. Satan and the demons are thought by Christians to be angels who rebelled against God and were expelled from Heaven. Within minutes generally another user would invariably try calling/chatting. However, for all practical purposes most Christian lay people know little or nothing of these views, and do not accept them. The technique was for the joker to put up an attractive profile with a girl’s name and picture, and put that profile into "Skype me" mode. Today, these views of angels are still technically acceptable within many mainstream Christian denominations. This unauthorised patch allowed a Skype user to masquerade as another user. Some medieval Christian philosophers were influenced by the views of Maimonides, and accepted his view of angels. In September 2005 a prank program was launched online. Certain Christian traditions, especially the Reformed tradition within Protestantism hold that references to the "Angel of the Lord" are references to pre-Incarnation appearances of Jesus. The down side of this is that it is easy to use the identity of a trusted person and trick a user to reveal information or execute a program sent to him. In the story of the 40 martyrs of Sebaste, in which 40 Christian Roman soldiers were made to stand naked on a frozen lake in the snow until they renounced their faith, angels were seen descending from Heaven placing the crowns of martyrs on their heads. This works two ways: you can use the system without revealing your identity to other users of the system, but on the other hand you have no guarantees that the person you communicate with is the one he says he is. Each consecrated altar has at least one angel always present offering up prayers, and a number of angels join the congregation when they meet to pray. Skype provides an uncontrolled registration system for users: registration requires no proof of the identity of the user at all. For instance, each Christian may be assigned a guardian angel at their baptism (although never defined by the Catholic or Orthodox churches, nevertheless it is personally held by many church members and most theologians). The mechanism and implementation has been examined in Bernson's report - referenced below. Some Christian traditions also hold that angels play a variety of specific roles in the lives of believers. data modified while traveling though peers, even if encrypted, is unknown and undocumented. For example the verse in Paul "our struggle is not with earthly things but with principalities and powers" (meaning according to most theologians the fallen angels of those choirs, used as an example of all the fallen angels). The integrity of the data, i.e. Many of these names come from verses in the bible which would appear at first to be referencing a literal thing, although retroactively suggesting that they really mention angels can also make sense in the context. The Skype server certifies each user's public key at log in. In this hierarchy, the Cherubim and Seraphim are typically closest to God, while the Angels and Archangels are most active in human affairs. The proprietary session establishment protocol is efficient and prevents both man-in-the-middle and replay attacks. The Celestial Hierarchy is the source of the names that have become part of tradition: Angels, Archangels, Principalities, Powers, Virtues, Dominions, Thrones, Cherubim, and Seraphim. Skype uses 1536-bit RSA (2048-bit RSA for customers who have purchased any "paid services" such as voicemail) to secure the pairwise negotiation of an AES symmetric session key over an untrusted channel. Some Christian traditions hold that angels are organized into three major hierarchies which are subdivided into orders called "Choirs", and list as many as ten orders of angels. Since a Skype connection may be routed through an intermediate peer, 256-bit AES encryption actively encodes the data stream of each call, or file transfer. The principle of continuity, however, seems to require the existence of beings intermediate between man and God. This would seem to be an admission that Skype relies on security through obscurity. The creeds and confessions do not formulate any authoritative doctrine of angels; and modern rationalism has tended to deny the existence of such beings, or to regard the subject as one on which we can have no certain knowledge. Would he make Skype open-source? No - that would make its strong 1024 bit encryption and security vulnerable: "We could do it but only if we re-engineered the way it works and we don't have the time right now.". Religious thought about the angels during the middle ages was much influenced by the theory of the angelic hierarchy set forth in The Celestial Hierarchy, a work of Pseudo-Dionysius the Areopagite, an unknown 5th century author or authors writing in the style of Dionysius the Areopagite. Niklas Zennstrom, co-founder of Skype, has admitted that the current security model would not withstand open-source scrutiny:. Furthermore, there are more angels than there are anything else in the universe (although when first written this would have probably not included atoms since atomic structure was not known). Stronger HDD caching does not seem to improve the situation. Angels possess the beatific vision, or the unencumbered understanding of God (the essence of the pleasure of heaven). This can severely reduce the lifespan of the HDD when Skype is running for a long time. They also teach that angels are intermediaries to some forces that would otherwise be natural forces of the universe, such as the rotation of planets and the motion of stars. In particular the continuous access pattern does not allow the disk to enter sleep or idle modes while Skype is active, even when offline. Scholastic theologians teach that angels are able to reason instantly, and to move instantly. Although those accesses are small, extremely fast and safe in the short term, they can be extremely harmful in the long term. Starting with the end of the 4th century, angels were depicted with wings, presumably to give an easy explanation for them travelling to and from heaven. This can be verified either by observing the HDD's activity LED or by using a file access monitor such as Filemon. (Hence the frequently recounted tale of Scholastics arguing about how many angels could fit on a pinhead; if angels possess physical bodies, the answer is "at most a finite number", if they do not, then we rule out any finite number greater than zero as the answer.) Seraphim are often depicted as six wings radiating from a center — either concealing a body, or without a body. Skype accesses the hard disk several times per minute. Angels are frequently depicted as human in appearance, though many theologians have argued that they have no physical existence. If the EICAR test file is sent over Skype's file transfer service, every major antivirus product appears to catch the virus and halt its transmission or reception via Skype. Indeed, the term "angel" frequently appears to describe not beings of power, but simply announcers of events. Skype's file transfer function does not contain any programmatic interfaces to antivirus products, but Skype claims to have tested its product against antivirus "Shield" products. An interpretation of the angels in the gospels is that angels are simply humans carrying a divine message. When run on Microsoft Windows, Skype binds to three ports on the user's computer and directly manipulates Windows XP's built-in firewall to accommodate these network bindings. Among other things, they are seen gathered around the Throne of God singing the thrice-holy hymn. Since the Skype code is proprietary and closed source the security of the software cannot be readily established. Angels fill a number of different roles in the Book of Revelation. The iLBC codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. When Peter was imprisoned, an angel put his guards to sleep, released him from his chains, and led him out of the prison. The codec is designed for narrowband speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbit/s with an encoding length of 20 ms. Two angels witnessed Jesus' ascent into Heaven and prophesied his return. iLBC (Internet Low Bit-rate Codec) is a free speech codec suitable for most voice communication over IP. Alternately, in Mark 16:5 the angel is not seen until the women enter the already-opened tomb, and he is described simply as "a young man." In Luke's version of the resurrection tale (Luke 24:4), two angels suddenly apparate next to the women within the tomb; they are described as being clothed in "dazzling apparel." This is most similar to the version in John 20:12, where Mary alone speaks to "two angels in white" within the tomb of Jesus. [3]. 28:2, an angel appeared at Jesus' tomb, frightened the Roman guards, rolled away the stone from the tomb, and later told the myrrh-bearing women of Jesus' resurrection. The Windows user interface was developed in Pascal using Delphi, while the Linux version is written in C++ with Qt and the Mac OS X version is written in Objective-C with Cocoa. In Matt. The Skype API allows other programs to use the Skype network to get "white pages" information and manage calls. The archangel Gabriel appeared to Mary in the traditional role of messenger to inform her that her child would be the Messiah, and other angels were present to herald his birth. The Skype client's application programming interface (API) exposes the network to software developers. There seems, however, no parallel to such a use of "angel", and it is doubtful whether the monarchical government of churches was fully developed when the Apocalypse was written. The Skype code is closed source and the protocol is proprietary which has raised suspicion and drawn broad criticism from software developers and the VoIP user communities. A less likely view is that the "angels" are the human representatives of the churches, the bishops or chief presbyters. This fact is not clearly communicated, however, and seems to contradict the license agreement which would limit Skype's utilisation of the user's "processor and bandwidth [to the] purpose of facilitating the communication between [the user] and other Skype Software users" (section 4.1). These are probably guardian angels, standing to the churches in the same relation that the "princes" in Daniel stand to the nations; practically the "angels" are personifications of the churches. The selection of intermediary computers is fully automatic, with individual users having no option to disable such use of their resources. we meet with the "Angels" of the Seven Churches of Asia Minor. This, however, puts an extra burden on those who connect to the Internet without NAT, as their computers and network bandwidth may be used to route the calls of other users. 1-3. Skype also routes calls through other Skype peers on the network, which allows it to traverse Symmetric NATs and firewalls, unlike most other VoIP programs (The two most common VoIP protocols, SIP and H323 are usually UDP and point-to-point, making NAT traversal problematic; see article). In Rev. The Skype user directory is entirely decentralised and distributed among the nodes in the network, which means the network can scale very easily to large sizes (currently just over forty million users) without a complex and costly centralised infrastructure. Angels occur in groups of four or seven (Rev 7:1). The main difference between Skype and other VoIP clients is that it operates on a peer-to-peer model rather than the more traditional server-client model. 2:10), thrones and dominions (Col 1:16). This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary. 8:38; Col. Each Skype user must have the Skype software running on his/her computer. 9:11); ranks are implied, archangels (Michael, Jude 9), principalities and powers (Rom. The Linux version runs on FreeBSD through its Linux binary compatibility. The distinction of good and bad angels is recognized; we have names, Gabriel (Luke 1:19), and Michael (Daniel 12:1), and the evil angels Beelzebub, (Mark 3:22) and Satan (Mark 1:13); while the allegiance of some angels are more ambiguous, such as Abaddon or Apollyon (Rev. Versions now exist for Microsoft Windows (Windows 2000, Windows XP and Windows CE (Pocket PC)), Mac OS X and GNU/Linux. The New Testament takes little interest in the idea of the angelic hierarchy, but there are traces of the doctrine. On 2006-01-05, version 2.0.0.69 of Skype was released. Naturally angels are most prominent in the Apocalypse. Its most significant new feature is the provision of centrally-stored contact lists so that a user's contact information is available from any computer that is connected to Skype (in other previous versions, contact information was stored on the local computer). (to Jesus), Luke 1:26 (to Mary), Acts 12:7 (to Peter)); and Jesus speaks of angels as fulfilling such functions (E.g. Mark 8:38, 13:27), implying in one saying that they neither marry nor are given in marriage (Mark 12:25). Skype Version 1.2 for Windows was released in March 23, 2005. In the New Testament angels appear frequently as the ministers of God and the agents of revelation (E.g. Matthew 1:20 (to Joseph), 4:11. This feature is only supported when running Windows XP. Others might perhaps view Maimonides's statements as being perfectly in keeping with the continued evolvement of Jewish thought over a period of several millennia. Skype 2.0 has a Skype Video Calling feature which has been implemented to enable videoconferencing. One can perhaps say that Maimonides thus presents a virtual rejection of the "classical" Jewish view of miracles; he and others substitute a rationalism that seems more appropriate for 20th and 21st century religious rationalists. Skype supports group chat with an interface similar to IRC. This is explained in his Guide of the Perplexed II:4 and II:6. This can be purchased separately and is automatically bundled in with SkypeIn. Instead, he says, the wise man sees that what the Bible and Talmud refer to as "angels" are actually metaphors for the various laws of nature, or the principles by which the physical universe operates, or kinds of platonic eternal forms. This service allows callers to leave voice-mail messages for Skype users who are not online, on another call or otherwise indisposed. Even this can be highly misleading: Maimonides harshly states that the average person's understanding of the term "angel" is ignorant in the extreme. Skype Voicemail was released on March 10, 2005. Rather, all such interactions are by way of angels. For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates. The rationalist view of angels, as held by Maimonides, Gersonides, Samuel Ibn Tibbon, etc., states that God's actions are never mediated by a violation of the laws of nature. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). In the Middle Ages, some Jews developed a rationalist view of angels that is still accepted by many Jews today. Cost is €30 for a twelve-month subscription, or €10 for a three-month subscription. Gabriel and Michael are mentioned in the book of Daniel, Raphael in the book of Tobit (from the Protestant Apocrypha or Catholic and Orthodox Deuterocanon) and the remaining four in the book of Enoch from the Old Testament Pseudepigrapha (considered canonical by the Ethiopian Orthodox). (Although France, Germany and Switzerland give SkypeIn numbers only to residents). The archangels named in post-exile Judaism are Gabriel, Michael, Raphael, Uriel, Raguel, Sariel, and Jerahmeel. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Germany, Sweden, Estonia, Switzerland, Poland and Brazil. Such a differing perspective on angels is discovered in the Book of Ezekiel, where these angels bear no relation whatsoever to the former understanding of what an angel was. SkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. Later biblical books in the Tanakh present a stunningly different view of angels, as the Jewish beliefs about such things developed over the many years covered in the Bible. In European Union countries, Luxembourg VAT of 15% is added to the charge, which makes the actual prices closer to €0.02 per minute. The earliest Biblical books present angels as heavenly beings created by God, some of whom apparently are endowed with free will. The current deposit is either €10 or €25, which automatically expires after 180 days of inactivity — a timer is reset after each successful SkypeOut connect. Traditional Jewish biblical commentators have a variety of ways of explaining what an angel is. Credit, which is necessary to use SkypeOut, is usually purchased via credit card, personal check or money order, or online services such as PayPal or Moneybookers. Many Bible chapters mention an "angry God" who sends His angel to smite the enemies of the Israelites. The Global Rate which is the one used for many countries, including nearly all First World countries, is currently 1.7 euro cents per minute. These include the warning to Lot of the imminent destruction of Sodom. This way, a SkypeOut user will be billed the same for a call placed to a telephone number in London, whether the user is calling from his/her computer in London itself, or from a different country. Angels appear in several Old Testament (Hebrew Bible) stories, in addition to the ones previously mentioned above. This rating method is used due to the fact that calls are rated the same regardless of place of origin. 2). Unlike international long-distance calls made from conventional telephones, which are traditionally rated according to the relative distance between countries, SkypeOut bills all calls according to the level of telecommunications liberalisation of the destination country, the volume of calls made from and to a given country, and access charges such as those to mobile (cell) phones. ix. SkypeOut is a paid feature of the Skype Internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world. 10) may have been affected by the representation of the seven archangels and also possibly by the seven amesha spentas of Zoroastrianism (compare Ezek. Conferences of up to five users are supported. 9, iv. The basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. iii. . The notion of the seven eyes (Zech. [2]. More than three hundred years before the Book of Daniel was written, Zechariah graded the angels according to their rank, but did not name them. In September 2005, in a deal generally criticised by many as overpriced [1], eBay acquired the company for $US 2.6 billion in cash and stock, plus an additional 1.5 billion in rewards if goals are met by 2008. Michael is Israel's representative in Heaven, where other nations—the Persians, for instance—were also represented by angelic princes. Skype users can speak to other Skype users for free, call traditional telephone numbers for a fee (SkypeOut), receive calls from traditional phones for a fee (SkypeIn), and receive voicemail messages for a fee. In Daniel, however, there occur the names Michael and Gabriel. The system has a reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. 30, the angels, when questioned, refuse to give their names. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. xxxii. Skype (IPA pronunciation: /skaɪp/, rhymes with type) is a proprietary peer-to-peer Internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA and competing against established open VoIP protocols like SIP or H.323. 18, and Gen.
This is the main contributor to its poor performance. i. reliance on a network (the Internet) over which there is little or no control of quality of service (QoS). In some places, it is implied that angels existed before the Creation (Gen. dropout and fizz;. 18, an angel brought the divine word to the prophet. time lag, often around 0.5 seconds, but occasionally up to two or three seconds, apparently caused by distant remote routing or the low bandwidth of either or both parties;. It is noteworthy that in I Kings, xiii. More than half of all users declined to state their sex. Thus the prophet Haggai was called God's messenger (angel); and it is known that "Malachi" is not a real name, but means "messenger" or "angel". Gender information is inconclusive so far. In the prophetic books, angels appear as representatives of the prophetic spirit, and bring to the prophets God's word. About 46% of Skypers are in Europe, but Brazil and China have the most Skype users of any country, each with 8.1% of the Skype population. 7). Average age: 29.7 years old. vi. February 3, 2006: Skype becomes fully integrated with popular online message board Bebo allowing registered users to call and IM eachother directly from their profiles. This conception was developed after the Exile; and in the Zechariah, angels of various shapes are delegated "to walk to and fro through the earth" in order to find out and report what happens (Zech.

Avenging angels are mentioned, such as the one in II Sam. 5, 6). xxxv. 9); the enemy is scattered before the angel like chaff (Ps. xxx. 35); messengers go forth from God "in ships to make the careless Ethiopians afraid" (Ezek. There are angels militant, one of whom smites in one night the whole Assyrian army of 185,000 men (II Kings, xix. 11). 7, xci. xxxiv. 5); and as God watched over Jacob, so is every pious person protected by an angel, who cares for him in all his ways (Ps. An angel brought Elijah meat and drink (I Kings, xix. 1), a human messenger of God is meant—addressed the whole people, swearing to bring them to the promised land. iii. 13, Mal. i. 19, Ḥag. xlii. 1) an angel of the Lord—unless here and in the preceding instances (compare Isa. In Judges (ii. 20.16). 23.20, Num. God sent an angel to protect the Hebrew people after their exodus from Egypt, to lead them to the promised land, and to destroy the hostile tribes in their way (Ex. Guardian angels were mentioned, but not, as was later the case, as guardian spirits of individuals and nations. Angels foretold to Abraham the birth of Isaac, to Manoah the birth of Samson, and to Abraham the destruction of Sodom. Angels reveal themselves to individuals as well as to the whole nation, in order to announce events, either good or bad, affecting humans. In the Bible, angels are a medium of God's power; they exist to execute God's will. 10]; certainly in Daniel), and there came to be various kinds of angels; some even being provided with names, as will be shown below. 9, iv. In post-Biblical times, the heavenly hosts became more highly organized (possibly as early as Zechariah [iii. 5 et seq.) and ofanim as heavenly beings who carry God's throne. i. 2) as having six wings; and Ezekiel describes the ḥayyot (Ezek. The seraphim are described by Isaiah (vi. 24). iii. 2, Gen. lxxx. 4, Ps. iv. God is described as riding on the cherubim and as "the Lord of hosts, who dwelleth between the cherubim"; while the latter guard the way of the Tree of Life (I Sam. When, however, the heavenly host is regarded in its most comprehensive aspect, a distinction may be made between cherubim, seraphim, ḥayyot ("living creatures"), ofanim ("wheels"), and arelim (another name for Thrones). V.). 49, R. lxxviii. 9; Ps. lxiii. 1; Isa. iii. 16; Mal. xxiv. 23; II Sam. 16; Job, xxxiii. xlviii. Angels are referred to in connection with their special missions as, for instance, the "angel which hath redeemed," "an interpreter," "the angel that destroyed," "messenger of the covenant," "angel of his presence," and "a band of angels of evil" (Gen. The inference, however, is not to be drawn that God Himself or one particular angel was designated: the expression was given simply to God's power to accomplish through but one angel any deed, however wonderful. Though the older writings usually mention one angel of the Lord, embassies to men as a rule comprised several messengers. 3): "Is there any number of his armies?" In the book of Revelation, the number is "a thousand thousands, and many tens of thousands". The general conception is the one of Job (xxv. 23). 6; Job, xxxiii. lxxxix. 1; Ps. 6, ii. 19; Job, i. 14, 15; I Kings, xxii. v. 2; Josh. xxxii. Jacob meets a host of angels; Joshua sees the "captain of the host of the Lord"; God sits on His throne, "all the host of heaven standing by Him on His right hand and on his left"; the sons of God come "to present themselves before the Lord" (Gen. The number of angels is enormous. 2). 18, xxv. 5; Job, iv. xiv. 28; Zech. 17, 20, xix. xiv. 25; II Sam. 20, lxxviii. ciii. When their duties are not punitive, angels are beneficent to man (Ps. Angels are portrayed as powerful and dreadful, endowed with wisdom and with knowledge of all earthly events, correct in their judgment, holy, but not infallible: they strive against each other, and God has to make peace between them. The use of wings suggests an original artistic convention merely intended to denote the figure as a spirit. Images of angels in Christian art are identical to prior depictions of gods such as Zeus, Eos, Eros, Thanatos and Nike, in pre-Christian classical art, and some divine beings in Mesopotamian art. They are commonly depicted with halos. 21), as they are described in the Bible, and depicted in Christian, Jewish and Zoroastrian art. ix. Angels are thought to possess wings (Dan. This imagery is very similar to the description of Jesus in the book of Revelation. 5, 6). x. In the Book of Daniel, reference is made to an angel "clothed in linen, whose loins were girded with fine gold of Uphaz: his body also was like the beryl, and his face as the appearance of lightning, and his eyes as lamps of fire, and his arms and his feet like in color to polished brass, and the voice of his words like the voice of a multitude" (Dan. 16, 30, as standing "between the earth and the heaven, having a drawn sword in his hand". xxi. A terrible angel is the one mentioned in I Chron. It is worth noting that these angels carry items that are contempory to the time in which they visit (perhaps angels are bound by the technology which humans have achieved). 8 et seq.). i. 2, Zech. ix. 13, Ezek. v. 23, Josh. xxii. Angels bear drawn swords or other destroying weapons in their hands—one carries an ink-horn by his side—and ride on horses (Num. Gradually, and especially in post-Biblical times, angels came to be bodied forth in a form corresponding to the nature of the mission to be fulfilled—generally, however, the human form. Though superhuman, angels can assume human form; this is the earliest conception. V.): "Who makes winds his messengers; his ministers a flaming fire." Some verses in the Apographya depict angels wearing blue or red robes but no such refrence occurs in the Protestant books. 4, R. civ. 15), as the Psalmist said (Ps. They are described as pure and bright as Heaven; consequently, they are said to be formed of fire, and encompassed by light (Job, xv. 2). iii. 11; Ex. 21, 22; II Kings, ii. 13; Judges, vi. xvi. Angels, or the Angel, appeared in the flames of the thorn bush (Gen. 9); some fly through the air; some become invisible; sacrifices touched by them are consumed by fire; and they may disappear in sacrificial fire, like Elijah, who rode to heaven in a fiery chariot. xxix. 6; II Sam. 17, xiii. 5; Judges, vi. 2, xix. xviii. In the Hebrew Bible, angels often appear to people in the shape of humans of extraordinary beauty, and often are not immediately recognized as angels (Gen. In Jewish apocalypses especially, the imagination ran riot on the rank, classes and names of angels; and such works as the various books of Enoch and the Ascension of Isaiah supply much information on this subject. 100. The development of the doctrine of an organized hierarchy of angels belongs to the Jewish literature of the period 200 BC to A.D. The guardian angels of the nations in Daniel probably represent the gods of the heathen, and we have there the first step of the process by which these gods became evil angels, an idea expanded by Milton in Paradise Lost. above), but they belong to a different order of thought from the angels of Judaism and of Christian doctrine; and the passage in no way suggests that the bne Elohim suffered any loss of status through their act. It is true that the bnē Elohim of that chapter are subordinate superhuman beings (cf. 6:2, as interpreted by the Book of Enoch. The Fall of the Angels is not properly a scriptural doctrine, though it is based on Gen. But in Tobit, we find Asmodeus the evil demon, τὸ πονηρὸν δαιμόνιον, who strangles Sarah's husbands, and also a general reference to "a devil or evil spirit", πνεῦμα (Tobit 3:8, 17; 6:7). In Daniel, the princes, or guardian angels, of the heathen nations oppose Michael, the guardian angel of Judah. The statement (Job 4:18) that God "charged his angels with folly" applies to all angels. In the canonical Hebrew/Aramaic scriptures, angels may inflict suffering as ministers of God, and Satan may act as accuser or tempter; but they appear as subordinates to God, fulfilling His will, and not as independent, morally evil agents. In Tobit, too, we find the idea of the demon or evil angel. 12:15.). (Tob. Again in Tobit a leading part is played by Raphael, "one of the seven holy angels". 8:16; 10:13, 20-21), he is the guardian of Israel's leading Kingdom of Judah. 160 BC, 71 angels, usually spoken of as "men" or "Angel-princes", appear as guardians or champions of the individual nations, defending them as God sits in council with them over the world; grades are implied, there are "princes" and "chief" or "great princes"; and the names of some angels are known, Gabriel, Michael; the latter is pre-eminent (Dan. In Daniel, c. During the Persian and Greek periods, the doctrine of angels underwent a great development, partly, at any rate, under foreign influences. 400 BC, there is no reference to angels, apart from the possible suggestion in the plural in Genesis 1:26. In the Priestly Code, c. The latter have been connected by Ewald and others with the later doctrine of seven chief angels (Tobit 12:15; Revelations 8:2), parallel to and influenced by the Ameshaspentas (Amesha Spenta), or seven great spirits of the Persian mythology. The seven angels of Ezekiel may be compared with the seven eyes of Yahweh in Zecharias 3:9, 4:10. In Psalms 78:49 the "evil angels" of the Authorized Version conveys a false impression; it should be "angels of evil", i.e. angels who inflict chastisement as ministers of God. 91:11, 103:20 &c.); they appear as ministers of God. Occasional references to "angels" occur in the Psalter (Pss. I Chronicles 21:1). Cf. Similarly in the Job the bne Elohim, sons of God, appear as attendants of God, and amongst them, Satan (Hebrew ha satan), again in the role of public prosecutor, the defendant being Job (Job 1, 2. The Satan also appears to prosecute (so to speak) the High Priest before the divine tribunal (Zecharias 3:1). Somewhat later, in the visions of Zechariah, angels play a great part; they are sometimes spoken of as "men", sometimes as mal'akh, and the Mal'akh Yahweh seems to hold a certain primacy among them (Zecharias 1:11). As in Genesis, they are styled "men"; mal'akh, for "angel", does not occur in Ezekiel. Ezekiel 9 gives elaborate descriptions of cherubim (a class, or type of angels); and in one of his visions, he sees seven angels execute the judgment of God upon Jerusalem. Ezekiel, as a prophet of the Exile, may have been influenced by the hierarchy of supernatural beings in the Babylonian religion, and perhaps even by the angelology of Zoroastrianism (it is not, however, certain that these doctrines of Zoroastrianism were developed at so early a date). Once the doctrine of monotheism was formally expressed, in the period immediately before and during the Exile (Deuteronomy 6:4-5 and Isaiah 43:10), we find angels prominent in the Book of Ezekiel. Nevertheless we may well suppose that polytheists in ancient Israel believed in superhuman beings other than Yahweh, but that the inspired writers have mostly suppressed references to them as unedifying. 7, or the passage, at any rate in its present form, may be exilic or post-exilic. An angel of I Kings 13:18 might be the Mal'akh Yahweh, as in 19:5, cf. Thus, the pre-exilic literature rarely mentions angels, or other superhuman beings other than Yahweh and manifestations of Yahweh; the pre-exilic prophets hardly mention angels. In Isaiah 6 the seraphim, superhuman beings with six wings, appear as the attendants of Yahweh. Similarly the "man" who wrestles with Jacob at Peniel is identified with God (Genesis 32:24, 30). In all these cases the angels, like the Mal'akh Yahweh, are connected with or represent a theophany. At Bethel, Jacob sees the angels of God on the ladder (Genesis 28:12), and later on they appear to him at Mahanaim (Genesis 32:1). 18:1 with 18:2, and note change of number in 19:17). (J) the appearance of Yahweh to Abraham and Lot is connected with three, afterwards two, men or messengers; but possibly in the original form of the story Yahweh appeared alone (Cf. In Genesis 18, 19. There are the cherubim who guard Garden of Eden. However, there are a few passages which speak of subordinate superhuman beings other than the Mal'akh Yahweh or Elohim. In earlier literature the Mal'akh Yahweh or Elohim is almost the only angel mentioned. Christians think that this foreshadows the doctrine of the Trinity, whereas Kabbalist Jews would show how it developed into kabbalistic theological thought and imagery. The identification of the Mal'akh Yahweh with the Logos, or Second Person of the Trinity, is not indicated by the references in the Hebrew scriptures; but the idea of a Being partly identified with God, and yet in some sense distinct from him, illustrates a tendency of Jewish religious thought to distinguish persons within the unity of the deity. The phrase Mal'akh Yahweh may have been originally a courtly circumlocution for the Divine King; but it readily became a means of avoiding anthropomorphism, and later on, when angels were classified, the Mal'akh Yahweh meant an angel of distinguished rank. The Mal'akh Yahweh (or Elohim) appears to Abraham, Hagar, Moses, Gideon, &c., and leads the Israelites in the Pillar of Cloud (Exodus 3:2). Those who see the Mal'akh Yahweh say they have seen God (Genesis 32:30; Judges 13:22). Exodus 3:2, with 3:4; 13:21 with 14:19). The Mal'akh Yahweh is an appearance or manifestation of Yahweh in the form of a man, and the term Mal'akh Yahweh is used interchangeably with Yahweh (cf. Prior to the emergence of monotheism in Israel the idea of an angel was the Mal'akh Yahweh, Angel of the Lord, or Mal'akh Elohim, Angel of God. The New Testament often speaks of "spirits," πνεύματα (Revelation 1:4). It is probable that the "hosts" were also identified with the armies of Israel, whether this army is human, or angelic. However, YHWH is very jealous of the distinction between Himself and angels, and consequently, the Hebrews were forbidden by Moses to worship the "host of heaven". The identification of the "hosts" with the stars comes to the same thing; the stars were thought of as being closely connected with angels.
