Genesis 30:14-15

One day during the wheat harvest Reuben found some mandrakes in the field and brought them home to his mother Leah. Rachel asked Leah, “Could I please have some of your son’s mandrakes?” Leah said, “Wasn’t it enough that you got my husband away from me? And now you also want my son’s mandrakes?” Rachel said, “All right. I’ll let him sleep with you tonight in exchange for your son’s mandrakes.”
