One day, the oldest daughter said to her sister, “Our father is old, and we have no hope of getting a husband and having children. Therefore, it’s up to us to preserve our father’s line for future generations. I have a plan. Let’s get our father drunk until he no longer knows what he’s doing. We’ll then have sex with him.”

The sister agreed, so that night they got their father drunk. The oldest daughter lay down with him. He didn’t know anything that happened.

The next day, the older daughter said to her sister, “Tonight it’s your turn. Remember, we’re doing this to preserve our father’s line.” So they got their father drunk, and the younger daughter lay down with him. Again, Lot didn’t know anything that happened.

Both daughters became pregnant by their father. The oldest sister gave birth to a son who became the father of the Moabites. The younger sister gave birth to a son who became the father of the Ammonites.
