The Book of Enoch is an ancient Hebrew apocalyptic religious text, ascribed by tradition to Enoch, the great-grandfather of Noah. Enoch contains unique material on the origins of demons and Nephilim, why some angels fell from heaven, an explanation of why the Genesis flood was morally necessary, and prophetic exposition of the thousand-year reign of the Messiah. Three books are traditionally attributed to Enoch, including the distinct works 2 Enoch and 3 Enoch, although none of the three books are considered canonical scripture by the majority of Jewish or Christian bodies.
