Now in the days of wheat harvest Reuben went and found mandrakes in the field, and brought them to his mother Leah. Then Rachel said to Leah, "Please give me some of your son's mandrakes."
But she said to her, "Is it a small matter for you to take my husband? And would you take my son's mandrakes also?" So Rachel said, "Therefore he may lie with you tonight in return for your son's mandrakes."
When Jacob came in from the field in the evening, then Leah went out to meet him and said, "You must come in to me, for I have surely hired you with my son's mandrakes." So he lay with her that night.
God gave heed to Leah, and she conceived and bore Jacob a fifth son.
Then Leah said, "God has given me my wages because I gave my maid to my husband." So she named him Issachar.
