33 And they gave their father wine to drink that night, and the firstborn went and lay with her father, but he did not know when she lay down or when she got up.
34 And it happened that, the next day the firstborn said to the younger one, “Look, I laid with my father last night. Let us give him wine to drink also tonight, then go and lie with him that we may secure descendants through our father.”
35 And they gave their father wine to drink again that night, and the younger got up and lay with him, but he did not know when she lay down or when she got up.
36 And the two daughters of Lot became pregnant by their father.
37 The firstborn gave birth to a son, and she called his name Moab. He is the father of Moab until this day.
38 And the younger, she also gave birth to a son, and she called his name Ben-Ammi. He is the father of the Ammonites until this day.
