Raphael is an archangel first mentioned in the Book of Tobit and in 1 Enoch, both estimated to date from between the 3rd and 2nd century BCE. In later Jewish tradition, he became identified as one of the three heavenly visitors entertained by Abraham at the Oak of Mamre. He is not named in either the New Testament or the Quran, but later Christian tradition identified him with healing and as the angel who stirred waters in the Pool of Bethesda in John 5:2–4, and in Islam, where his name is Israfil, he is understood to be the unnamed angel of Quran 6:73, standing eternally with a trumpet to his lips, ready to announce the Day of Judgment. In Gnostic tradition, Raphael is represented on the Ophite Diagram.

Archangels are the second-lowest rank of angel in the Christian hierarchy of angels, put forward by Pseudo-Dionysius the Areopagite in the 5th or 6th century in his book De Coelesti Hierarchia. The word "archangel" itself is usually associated with the Abrahamic religions, but beings that are very similar to archangels are found in a number of other religious traditions.
