Genesis 19:29-38

29 When God destroyed the cities on the plain, he remembered Abraham. Lot was allowed to escape from the destruction that came to the cities where he was living.
30 Lot left Zoar because he was afraid to stay there. He and his two daughters settled in the mountains where they lived in a cave.
31 The older daughter said to the younger one, "Our father is old. No men are here. We can't get married as other people do.
32 Let's give our father wine to drink. Then we'll go to bed with him so that we'll be able to preserve our family line through our father."
33 That night they gave their father wine to drink. Then the older one went to bed with her father. He didn't know when she came to bed or when she got up.
34 The next day the older daughter said to the younger one, "I did it! Last night I went to bed with my father. Let's give him wine to drink again tonight. Then you go to bed with him so that we'll be able to preserve our family line through our father."
35 That night they gave their father wine to drink again. Then the younger one went to bed with him. He didn't know when she came to bed or when she got up.
36 So Lot's two daughters became pregnant by their father.
37 The older one gave birth to a son and named him Moab. He is the ancestor of the Moabites of today.
38 The younger daughter also gave birth to a son and named him Ben Ammi. He is the ancestor of the Ammonites of today.
