Genesis 19:33-35

International Standard Version

³³ So they had their father drink wine that night, and the older one had sexual relations with her father, but he was not aware when she lay down or when she got up. ³⁴ The next day the firstborn told the younger one, “Look! I had sex with my father last night. Let’s make him drink wine tonight again as well. Then you have sex with him, too. That way we’ll preserve our father’s lineage.” ³⁵ So they made their father drink wine that night as well, so he was not aware when she lay down or when she got up.
