They called out to Lot and said, “Where are the men who came to you tonight? Send them out to us so we can have sex with them!”

The next day the firstborn said to the younger, “Look, I slept with my father last night. Let’s get him to drink wine again tonight so you can go sleep with him and we can preserve our father’s line.”

And she said unto her, Is it a small matter that thou hast taken my husband? and wouldest thou take away my son's mandrakes also? And Rachel said, Therefore he shall lie with thee to night for thy son's mandrakes.

When Jacob came in from the field that evening, Leah went to meet him and told him, "You're having sex with me tonight. I traded my son's mandrakes for you!" So he slept with her that night.
