Genesis 6 is one of the strangest passages in the Bible. The "sons of God" take human wives, and their children are the Nephilim — "the mighty men who were of old, men of renown." Then the flood comes. The text barely pauses to explain it. The Book of Enoch, read as scripture for centuries, tells the fuller version Genesis only gestures at.
"There were giants in the earth in those days… mighty men which were of old, men of renown." — Genesis 6:4
Who the Nephilim and Watchers were
In Enoch, two hundred angels called Watchers — set to watch over humanity — descend on the summit of Mount Hermon under their leader Shemihazah and swear a mutual oath to break their charge. They take human wives. Their children are the Nephilim, the giants. The Watchers also teach humanity things it was not ready for: the forging of weapons, sorcery, the cutting of roots and charms, cosmetics, and the reading of the stars. The giants devour the earth's provision, and the whole order unravels toward the flood.
Ancient texts give enormous figures — some manuscripts of Enoch describe giants of towering height, and later traditions pile the numbers higher. The honest answer is that the surviving texts disagree and the numbers are symbolic as much as literal: the point was that they were monstrous, beyond human scale, a wrongness in the world.

Enoch gives a direct answer that shaped early Christian thinking: when the Nephilim died, their spirits were not allowed to rest. As the offspring of flesh and fallen angels, they became the "evil spirits" that roam the earth — the origin of demons. It is one of the oldest explanations of unclean spirits we have.

Metalworking and weapons (through Azazel), enchantments and root-cutting, astrology and the signs of the heavens. The theme is forbidden knowledge — power handed to humanity before it was ready, and the ruin that followed. The forbidden lessons →
Why this story was kept quiet
A tale of named angels, towering giants, and a cosmic rebellion was hard for a tidy, settled theology to carry. The fuller account lived in the Book of Enoch, which the West let slip away while Ethiopia kept it whole. But the story never fully left — it echoes in Peter and Jude, in the "spirits in prison," and in the long memory of the giants before the flood.
