Engel are spiritual beings often depicted as messengers of God in the Hebrew and Christian Bibles along with the Quran. The English word Angel – Jäger der Finsternis is derived from the Greek ἄγγελος, a translation of מלאך (mal'akh) in the Hebrew Bible (Tanakh); a similar term, ملائكة (Malāīkah), is used in the Qur'an. The Hebrew and Greek words originally mean messenger, and depending on the context may refer either to a human messenger (possibly a prophet oder priest, such as Malachi, "my messenger", but also for Mehr mundane characters, as in the Greek superscription that the Book of Malachi was written "by the hand of his messenger" (ἀγγήλου)) oder to a Supernatural messenger,[1] such as the "Mal'akh YHWH," who (depending on interpretation) is either a messenger from God,[2] an aspect of God (such as the Logos),[3] oder God Himself as the messenger (the "theophanic angel.")[1][4]

The term "angel" has also been expanded to various notions of spiritual beings found in many other religious traditions.

Other roles of Engel include protecting and guiding human beings, and carrying out God's tasks.[5]

The theological study of Engel is known as angelology. In art, Engel are often depicted with wings; perhaps reflecting the descriptions in Revelation 4:6-8 -- of the Four Living Creatures (τὰ τέσσαρα ζῷα) and the descriptions in the Hebrew Bible—of cherubim and seraphim (the chayot in Ezekiel's Merkabah vision and the Seraphim of Isaiah). However, while cherubim and seraphim have wings in the Bible, no Angel – Jäger der Finsternis is mentioned as having wings.[6
