Genesis 30:14-15

30:14 At the time of the wheat harvest Reuben went out and found some mandrake plants in a field and brought them to his mother Leah. Rachel said to Leah, “Give me some of your son’s mandrakes.” 30:15 But Leah replied, “Wasn’t it enough that you’ve taken away my husband? Would you take away my son’s mandrakes too?” “All right,” Rachel said, “he may sleep with you tonight in exchange for your son’s mandrakes.”
