Genesis 19:34-36

New Living Translation

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.” ³⁵ So that night they got him drunk with wine again, and the younger daughter went in and had intercourse with him. As before, he was unaware of her lying down or getting up again.

³⁶ As a result, both of Lot’s daughters became pregnant by their own father.
