The Nephilim appear in brief biblical passages and in later traditions about giants. Different texts should be distinguished before their accounts are combined.
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.
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.
1 Enoch brings together accounts of heavenly beings, judgment, celestial order, and righteousness. It is a composite work rather than a single continuous biography of Enoch.
