Gabriel, in the Abrahamic religions, is an angel who typically serves as God's messenger. Gabriel is mentioned in both the Old and New Testaments of the Bible. In the Old Testament, he appears to the prophet Daniel, explaining Daniel's visions (Daniel 8:15–26, 9:21–27). In the Gospel of Luke, Gabriel appeared to Zechariah and the Virgin Mary, foretelling the births of John the Baptist and Jesus, respectively (Luke 1:11–38). In the Book of Daniel, he is referred to as “the man Gabriel”, while in the Gospel of Luke, Gabriel is referred to as “an angel of the Lord” (Luke 1:11). Gabriel is not called an archangel in the Bible, but is so called in Intertestamental period sources like the Book of Enoch. In the Roman Catholic, Eastern Orthodox, and Anglican churches, the archangels Michael, Raphael, and Gabriel are also referred to as saints. In Islam, Gabriel is considered an archangel whom God is believed to have sent with revelation to various prophets, including Muhammad. The 96th chapter of the Quran, The Clot, is believed by Muslims to have been the first chapter revealed by Gabriel to Muhammad.
