Genesis 19:33-34

New Living Translation

³³ So that night they got him drunk with wine, and the older daughter went in and had intercourse with her father. He was unaware of her lying down or getting up again.

³⁴ The next morning the older daughter said to her younger sister, “I had sex with our father last night. Let’s get him drunk with wine again tonight, and you go in and have sex with him. That way we will preserve our family line through our father.”
