"And there was great impiety and much fornication, and they went astray and all their ways became corrupt" (1 En 8:1-2). This wickedness caused Enoch to have a sleep-vision or prophetic dream, known as the 'Animal Apocalypse', which relates how In the Book of Giants, found at Qumran, Samyaza, through this forbidden action, fathers two half-breed giant sons, Ohya and Hahyah. The Watchers shared with humankind various forbidden arts, sciences, and celestial "secrets" or "mysteries" of the true heavenly gnosis or knowledge — especially that Wisdom possessed by Azazel, who taught them also the secrets of magic, of war (including metallurgy and weaponry) and of seductive ornamentation (including jewelry and cosmetics) — all of which ultimately brought down the wrath of Heaven upon the rebel angels and their spawn. God commanded the angel Gabriel to cause the Watchers and giants to wage civil war: Finally, the judgement of the Watcher-associates of Samyaza is described. Once the archangels and the host of the righteous had punished the Watchers and giants, God poured forth, after several generations, the Great Flood of Noah to wipe out the lingering remnants of the corrupted races of Earth. Through the diluvial judgment, God swept away the last of the lawlessness that had been unleashed by the forbidden knowledge of the Watchers, re-establishing His covenant with Noah and his sons and restoring harmony and fertility to the Earth. Book of Giants In The Book of Giants, Shemyaza (or Šahmīzād in the Manichaean version) begets two sons, who together battle Leviathan. However, they are not portrayed as heroic, but as boasting about their own victory; a symbol of royal failure to keep one's power in this world. After the defeat of the Leviathan, Shemyaza and his offspring are slain by the four punishing angels. Babylonian Talmud The Babylonian Talmud contains a singular mention of the name Samyaza (spelled שמחזאי in the Vilna edition with some lesser variations in the manuscripts) in Niddah 61a. Accordingly: The text does not elucidate the identity of Samyaza who appears nowhere else in the corpus, but clearly portrays him as the grandfather of Og, the king of Bashan and the last of Rephaim known for his gigantic height and strength (Deuteronomy 3:11). As such this can be taken as a reference to the myth of the fallen angels and the motif of their gigantic progeny transmitted in apocrypha and pseudepigrapha. Other traditions In
