Genesis 19:33-35

Complete Jewish Bible

³³ So they plied their father with wine that night, and the older one went in and slept with her father; he didn’t know when she lay down or when she got up. ³⁴ The following day, the older said to the younger, “Here, I slept last night with my father. Let’s make him drink wine again tonight, and you go in and sleep with him, and that way we’ll enable our father to have descendants.” ³⁵ They plied their father with wine that night also, and the younger one got up and slept with him, and he didn’t know when she lay down or when she got up.
