Gabriel

Gabriel, an angel, one of the seven archangels, “the power of God,” who is represented in the traditions of both the Jews and the Moslems as discharging the highest functions, and in Christian tradition as announcing to the Virgin Mary her election of God to be the mother of the Messiah; he ranks fully higher among Moslems than Jews.
