51:5.7

But children of adulterers will not come to maturity. The seed of an unlawful union will vanish away.

When men began to multiply on the surface of the ground, and daughters were born to them, God’s sons saw that men’s daughters were beautiful, and they took any that they wanted for themselves as wives. Yahweh said, “My Spirit will not strive with man forever, because he also is flesh; so his days will be one hundred twenty years.” The Nephilim were in the earth in those days, and also after that, when God’s sons came in to men’s daughters and had children with them. Those were the mighty men who were of old, men of renown.

Now when these things were done, the principal men came to me and said, “The nation of Israel, the princes, the priests, and the Levites haven’t put away from themselves the foreign people of the land nor the uncleannesses of the Gentiles—the Canaanites, Hittites, Pherezites, Jebusites, Moabites, Egyptians, and Edomites. For both they and their sons have married with their daughters, and the holy seed is mixed with the foreign people of the land. From the beginning of this matter the rulers and the nobles have been partakers of this iniquity.”
