Genesis 19:30-36

Lot and His Daughters 30Lot and his two daughters left Zoar and settled in the mountains, for he was afraid to stay in Zoar. He and his two daughters lived in a cave. 31One day the older daughter said to the younger, “Our father is old, and there is no man around here to give us children—as is the custom all over the earth.

32Let’s get our father to drink wine and then sleep with him and preserve our family line through our father.”

33That night they got their father to drink wine, and the older daughter went in and slept with him. He was not aware of it when she lay down or when she got up. 34The next day the older daughter said to the younger, “Last night I slept with my father. Let’s get him to drink wine again tonight, and you go in and sleep with him so we can preserve our family line through our father.”

35So they got their father to drink wine that night also, and the younger daughter went in and slept with him. Again he was not aware of it when she lay down or when she got up. 36So both of Lot’s daughters became pregnant by their father.
