Genesis 19:30-38 - Lot And His Daughters
30 Lot was afraid to stay in Zoar. So he and his two daughters moved up into the hills and lived in a cave. 31 The older daughter said to her sister: Our father is getting old. There are no men in the whole world to marry us so we can have children. 32 Come, let us get our father drunk. Then we can sleep with him and have children by him. 33 That night they gave him wine to drink. The older daughter had intercourse with him. But he was so drunk that he did not know it.
34 The next day the older daughter said to her sister: I slept with him last night. Let us get him drunk again tonight, and you sleep with him. Then each of us will have a child by our father. 35 So that night they got him drunk. The younger daughter had intercourse with him. Again he was so drunk that he did not know it.
36 Both of Lot's daughters became pregnant by their own father. 37 The older daughter had a son, whom she named Moab. He was the ancestor of the present-day Moabites. 38 The younger daughter also had a son, whom she named Ben-ammi. He was the ancestor of the present-day Ammonites.
