The Book of Giants names a fragmentary Jewish Enochic work represented at Qumran and a related Manichaean adaptation. Its surviving witnesses concern the offspring of the Watchers, ominous dreams, Enoch, and impending judgment.
Fallen angels are heavenly beings portrayed as losing their place or proper condition through transgression. Enochic descent, Satan’s refusal to honor Adam, and the war in Revelation are distinct accounts that later interpretation can bring together.
The Watchers are heavenly beings whose descent, teachings, and punishment are narrated in 1 Enoch. Their literary identity must be distinguished from later religious interpretations.
