Genesis 19:35-37

New Living Translation

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. ³⁷ When the older daughter gave birth to a son, she named him Moab.^[a] He became the ancestor of the nation now known as the Moabites.
