Genesis 19:33-35

Christian Standard Bible

³³ So they got their father to drink wine that night, and the firstborn came and slept with her father; he did not know when she lay down or when she got up.

³⁴ The next day the firstborn said to the younger, “Look, I slept with my father last night. Let’s get him to drink wine again tonight so you can go sleep with him and we can preserve our father’s line.” ³⁵ That night they again got their father to drink wine, and the younger went and slept with him; he did not know when she lay down or when she got up.
