Genesis 19:33-35

Living Bible

³³ So they got him drunk that night, and the older girl went in and had sexual intercourse with her father; but he was unaware of her lying down or getting up again.

³⁴ The next morning she said to her younger sister, “I slept with my father last night. Let’s fill him with wine again tonight, and you go in and lie with him, so that our family line will continue.” ³⁵ So they got him drunk again that night, and the younger girl went in and lay with him, and, as before, he didn’t know that anyone was there.
