THE SINS of the “sons of God” mentioned in Genesis 6:1–4 are listed in detail in chapters 6 through 8 of the Book of 1 Enoch. 

Specifically, the rebellious Watchers “defile[d] themselves” by commingling with women and taught humanity things we weren’t supposed to know—the making of weapons, sorcery, beguilement, enticement, and venerating the sun, moon, and the host of heaven. 

The monstrous offspring produced by these unholy unions became an existential threat to humankind, eating the produce of human labor and, when that was gone, eating humans. Not content to contaminate the human genome, “they began to sin against the birds and beasts and creeping things and the fish, and to devour one another’s flesh. And they drank the blood.” (1 Enoch 7:3–5) 

In short, the Nephilim were consummate evil. Next month, we’ll discuss the intercession of the archangels Michael, Sariel (or Uriel), Raphael, and Gabriel on behalf of humanity.
