Genesis 19:30-38

30Lot went up from Zoar, and 12stayed in the 3mountains, and his two daughters with him; for he was afraid to 4stay in Zoar; and he 5stayed in a cave, he and his two daughters.

31Then the firstborn said to the younger, “Our father is old, and there is not a man 6on earth to 7come in to us after the manner of the earth.

32Come, 8let us make our father drink wine, and let us lie with him that we may preserve 9our family through our father.”

33So they made their father drink wine that night, and the firstborn went in and lay with her father; and he did not know when she lay down or when she arose.

34On the following day, the firstborn said to the younger, “Behold, I lay last night with my father; let us make him drink wine tonight also; then you go in and lie with him, that we may preserve 10our family through our father.”

35So they made their father drink wine that night also, and the younger arose and lay with him; and he did not know when she lay down or when she arose.

36Thus both the daughters of Lot were with child by their father.

37The firstborn bore a son, and called his name 11Moab; he is the father of the Moabites to this day.

38As for the younger, she also bore a son, and called his name Ben-ammi; he is the father of the 12sons of 13Ammon to this day.
