Genesis 30:14-15

During the wheat harvest Reuben went into the field and found some mandrake plants and brought them to his mother Leah. But Rachel said to Leah, “Please give me some of your son’s mandrakes.” Leah answered, “You have already taken away my husband, and now you are trying to take away my son’s mandrakes.” But Rachel answered, “If you will give me your son’s mandrakes, you may sleep with Jacob tonight.”
