Genesis 6:1-2,4
When people began being numerous on earth, and daughters had been born to them, the sons of God, looking at the women, saw how beautiful they were…
…and married as many of them as they chose. In those days, and even afterward, giants lived on the earth, for whenever the sons of God had intercourse with human women, they gave birth to children who became the heroes mentioned in legends of old.
Genesis 19:5-8
They called to Lot, and said to him, ‘Where are the men who came to you tonight? Bring them out to us, so that we may have sex with them.’ Lot went out the door, and shut the door behind him. He said, ‘Please, my brothers, do not be evil.’ ‘Look, I have two virgin daughters. Please let me bring them out to you. You may do whatever you please to them, just do not do anything to these men, for they have come under the protection of my roof.’
Genesis 19:30-36
Lot went up out of Zoar, and lived in the mountain, and his two daughters with him; for he was afraid to live in Zoar. He lived in a cave with his two daughters. The firstborn said to the younger, “Our father is old, and there is not a man in the earth to come in to us after the manner of all the earth. Come, let’s make our father drink wine, and we will lie with him, that we may preserve our father’s seed.” They made their father drink wine that night: and the firstborn went in, and lay with her father. He didn’t know when she lay down, nor when she arose. It came to pass on the next day, that the firstborn said to the younger, “Behold, I lay last night with my father. Let us make him drink wine again, tonight. You go in, and lie with him, that we may preserve our father’s seed.” They made their father drink wine that night also. The younger arose, and lay with him. He didn’t know when she lay down, nor when she arose. Thus both of Lot’s daughters were with child by their father.
Leviticus 20:
20:1 Yahweh spoke to Moses, saying,
20:2 "Moreover, you shall tell the children of Israel, 'Anyone of the children of Israel, or of the strangers who live as foreigners in Israel, who gives any of his seed to Molech; he shall surely be put to death. The people of the land shall stone him with stones.
20:3 I also will set my face against that person, and will cut him off from among his people because he has given of his seed to Molech, to defile my sanctuary, and to profane my holy name.
20:4 If the people of the land all hide their eyes from that person, when he gives of his seed to Molech, and don’t put him to death;
20:5 then I will set my face against that man, and against his family, and will cut him off, and all who play the prostitute after him, to play the prostitute with Molech, from among their people.
