The Nephilim are mysterious beings mentioned in the Bible (Genesis 6:4; Numbers 13:33) and in extra-biblical texts like the Book of Enoch, often described as giant, powerful offspring of divine beings ("sons of God") and human women, who are said to have existed before the great flood and later in Canaan. Their name comes from the Hebrew naphal ("to fall"), meaning "fallen ones," and they represent a lineage of legendary, strong figures, possibly monstrous giants, who brought violence and corruption, leading to divine judgment. Interpretations vary, from literal hybrids to metaphors for corrupted heroes or powerful clans.
