Genesis 30:14-16

14One day during the wheat harvest, Reuben found some mandrakes growing in a field and brought them to his mother, Leah. Rachel begged Leah, “Please give me some of your son’s mandrakes.”

15But Leah angrily replied, “Wasn’t it enough that you stole my husband? Now will you steal my son’s mandrakes, too?” Rachel answered, “I will let Jacob sleep with you tonight if you give me some of the mandrakes.”

16So that evening, as Jacob was coming home from the fields, Leah went out to meet him. “You must come and sleep with me tonight!” she said. “I have paid for you with some mandrakes that my son found.” So that night he slept with Leah.
