Genesis 19:33-36

New American Standard Bible

³³ So they made their father drink wine that night, and the firstborn went in and slept with her father; and he did not know when she lay down or got up. ³⁴ On the following day, the firstborn said to the younger, “Look, I slept last night with my father; let’s make him drink wine tonight too, then you go in and sleep with him, so that we may keep ^[a]our family alive through our father.” ³⁵ So they had their father drink wine that night too, and the younger got up and slept with him; and he did not know when she lay down or got up. ³⁶ And so both of the daughters of Lot conceived by their father.
