Genesis 30:15-17

But 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.” So 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. And God answered Leah’s prayers. She became pregnant again and gave birth to a fifth son for Jacob.
