Genesis 19:34-36

New Catholic Bible

³⁴ The next day the older sister said to the younger, “Behold, yesterday I slept with my father. Let us make him drink wine tonight as well and you can sleep with him. Thus, we will provide descendants for our father.” ³⁵ That night as well they made their father drink wine, and the younger sister slept with him. He did not realize what had happened, not even when she lay down or when she got out of bed.

³⁶ Thus, the two daughters of Lot conceived children for their father.
