Genesis 30:14-30:27
Once, at the time of the wheat harvest, Reuben came upon some mandrakes in the field and brought them to his mother Leah. Rachel said to Leah, "Please give me some of your son's mandrakes." But she said to her, "Was it not enough for you to take away my husband, that you would also take my son's mandrakes?" Rachel replied, "I promise, he shall lie with you tonight, in return for your son's mandrakes." When Jacob came home from the field in the evening, Leah went out to meet him and said, "You are to sleep with me, for I have hired you with my son's mandrakes." And he lay with her that night. God heeded Leah, and she conceived and bore him a fifth son. And Leah said, "God has given me my reward for having given my maid to my husband." So she named him Issachar.
When Leah conceived again and bore Jacob a sixth son, Leah said, "God has given me a choice gift; this time my husband will exalt me, for I have borne him six sons." So she named him Zebulun. Last, she bore him a daughter, and named her Dinah. Now God remembered Rachel; God heeded her and opened her womb. She conceived and bore a son, and said, "God has taken away my disgrace." So she named him Joseph, which is to say, "May the Lord add another son for me."
After Rachel had borne Joseph, Jacob said to Laban, "Give me leave to go back to my own homeland. Give me my wives and my children, for whom I have served you, that I may go; for well you know what services I have rendered you." But Laban said to him, "If you will indulge me, I have learned by divination that the Lord has blessed me on your account."
