An angel (Hebrew: מלאך; mal'ach, Arabic: ملاك, malak, Latin angelus, Ancient Greek: ἄγγελος, Angelos) is a supernatural, intelligent being, which is found in various (often monotheistic) religions. In Christianity, Islam, Judaism and Zoroastrianism, act angels, as attendants or guardians to man, typically act as messengers from God (or the gods), of which they are clearly distinguishable, and possess superhuman abilities and characteristics. In other religions supernatural beings are sometimes likened to angels because they have some characteristics in common with angels and serve as angel-like. The word angel comes from the Greek ἄγγελος, Angelos that "messenger" means. The Hebrew word for angel is מלאך, mal'ach, which also means "messenger." The Arabic word ملاك, malak, is etymologically related thereto. The term 'angel' in itself indicates no divine essence. As the author of the last book of the Old Testament is referred to as "Malachi" - "my messenger" and called the pastors of the seven churches in the book of Revelation "aggeloo. Engelen can assume an arbitrary external form. In the Christian tradition, angels often have a perfect human appearance, is often that of a young man, though angels are sexless. In the stories from the Bible angels are in some cases not initially recognized as such by humans. For example, see Genesis 18 (which later turns out who the visitors), Judges 13:21 (where the visitor impresses but only on his departure as an angel is recognized). This is also mentioned in Islam: Muhammad thought so, at the appearance of Archangel Gabriel, having to deal with a jinn. Sometimes angels come in the form of a fearsome and light-emitting substance, and their appearance to humans physically almost unbearable. Angels are - in art and in instance icons - usually depicted as creatures with wings. This is understandable, as there are bound connection with heaven maintained. Yet there are no texts in the Bible and in Jewish scriptures where angels when they come to deliver a message, to have such an appearance; Jacob saw angels example using a (Jacobs) ladder descend from the sky. Different is that with angels proclaim the greatness of God, as in Isaiah 6 (seraphim with six wings) and Ezekiel 1 (creatures with four wings). In the Qur'an, in the first verse of Surah 35 "The Founder" (فاطر) indeed written that angels have wings "two, three and four." The way in which angels are depicted largely based on convention are human angels, supernatural and incorporeal beings, not portray truthfully off. In the tradition of orthodox Christianity are often referred to as cherubim "veelogig" and Seraphim as "zesvleugelig", these do have a human form. This corresponds with what to read in Isaiah 6 about seraphim. In the iconography depicted as six-winged seraphim, flaming creatures who cover their face and legs with their wings awe of the majesty of God.
