Nephilim

In the Hebrew Bible (notably Genesis 6:1–4) the Nephilim appear in a brief, ambiguous account linking them to the antediluvian world and to the phrase 'mighty men of old.' In later Second Temple literature (e.g., 1 Enoch, Jubilees, influential in later interpretation) a prominent tradition presents them as the offspring of rebellious heavenly beings (the Watchers) and human women; this tradition frames their origin as a boundary-crossing between divine and human realms that contributes to cosmic disorder and helps precipitate divine judgment (the Flood). Alternative scholarly readings treat references to the Nephilim as memories or literary labels for elite/royal warriors or legendary pre-Israelite powerful figures rather than necessarily supernatural progeny.

The biblical corpus itself gives limited physical detail. Many ancient translations (Septuagint, Theodotion, Vulgate, Targums) render the Hebrew term as 'giants,' and later references (e.g., Numbers 13:33) describe inhabitants encountered in Canaan as formidable and of great stature, leading to a long-standing association with extraordinary size and strength. Scholarly commentary notes this size-language may reflect later interpretive tradition, rhetorical exaggeration, or memories of impressive monuments rather than precise physical description in the earliest texts.

Across the testimonial and interpretive traditions the Nephilim are associated with exceptional strength, status, or prowess (the Bible's 'mighty men of old'), and in Second Temple accounts they are portrayed as destructive and corrupting figures whose behavior contributes to moral and cosmic disorder. Some translations and etymological proposals emphasize violent or domineering behavior ('the violent ones' or 'those who cause others to fall'). Other scholarly readings recast references as descriptions of elite warriors or legendary powerful figures rather than necessarily supernatural monsters.
