Why the Watchers Fell and the Giants Drowned in the Flood
The Watchers descended from heaven, fathered giants, and watched the Flood answer a world whose boundaries had been broken beyond repair.

The Sons of God Come Down
Genesis 6:4 gives the Nephilim one sentence and no explanation. The sons of God came to the daughters of men and fathered mighty men of old, men of renown. No names. No motive. No accounting for what happened to them. The crack in the text is just wide enough to see through, not wide enough to see clearly.
The Book of Jubilees, a Jewish rewriting of Genesis composed in the second century BCE, opened that crack into a full narrative. Angels had been sent to earth to instruct humanity. The tragedy begins because the line between teacher and trespasser collapses. Knowledge meant to guide human life becomes entangled with appetite, bodies, and children too large for the world that receives them.
The Angels Leave Their Station
Jubilees calls them the Watchers, the ones who were set to watch over the children of men. They were, in the tradition's framing, a deliberate assignment. Heaven recognized that humanity needed guidance in the practical arts of survival, agriculture, metalwork, the navigation of seasons. Watchers were sent to provide it.
What happens next is not a dramatic fall but a slow collapse of role. The Watchers look at the daughters of men and find them beautiful. They do not consult heaven about this. They act on it. The decision to come down fully, to take wives, to begin families in flesh, is a decision made without authorization, the same overconfidence in personal judgment that the tradition identifies in other catastrophes. The angels know more than the humans they were sent to teach. That knowing does not save them from acting as badly as the humans they judged.
The Names the Aramaic Tradition Supplies
The Targum Pseudo-Jonathan on Genesis, the Aramaic paraphrase of the Torah composed roughly in the seventh or eighth century CE, inserts names directly into Genesis 6:4: Shemhazai and Azzael. These two figures became the central Watchers in the Aramaic and Aramaic-influenced tradition. Shemhazai leads the descent. Azzael teaches humanity the manufacture of weapons and the arts of seduction and corruption.
Later traditions, preserved in Louis Ginzberg's Legends of the Jews (1909-1938 CE) from earlier aggadic sources, fill in what the Book of Jubilees and the Targum leave open. Shemhazai eventually repents, hanging himself between heaven and earth, suspended between the world he abandoned and the divine realm he can no longer reach. Azzael does not repent. He is bound and buried in darkness. The two fates represent the tradition's two assessments of what the fallen angels became: one that could recognize its own wrong and one that could not.
The Giants and the Flood
The children of the Watchers are giants, creatures whose size matches the scale of the violation that produced them. They consume everything. The earth cannot produce enough to feed them. They turn to the animals. They turn to each other. The boundary-breaking that began with angels crossing into human bodies produces children for whom no boundary holds at all.
The Flood, in the tradition's accounting, is the answer to this. It is not simply punishment for human wickedness, though human wickedness is real in the narrative. It is the correction of a world that has been structurally violated. When the beings set to guard the structure of creation become the first to break it, the result is a cascade that only total reset can address. The giants die in the water. Their spirits, the tradition says, persist as the demons that haunt the post-diluvian world, bound to the earth without bodies, still hungry, still boundary-less.
