14 While the wheat harvest was being gathered, Reuben went out into the fields. He found some mandrake plants. He brought them to his mother Leah. Rachel said to Leah, "Please give me some of your son's mandrakes."
15 But Leah said to her, "Isn't it enough that you took my husband away? Are you going to take my son's mandrakes too?" Rachel said, "All right. Jacob can make love to you tonight if you give me your son's mandrakes."
16 Jacob came in from the fields that evening. Leah went out to meet him. "You have to sleep with me tonight," she said. "I've bought you with my son's mandrakes." So he made love to her that night.
17 God listened to Leah. She became pregnant and had a fifth son by Jacob.
18 Then Leah said, "God has rewarded me because I gave my female servant to my husband." So she named the boy Issachar.
19 Leah became pregnant again. She had a sixth son by Jacob.
20 Then Leah said, "God has given me a priceless gift. This time my husband will treat me with honor. I've had six sons by him." So she named the boy Zebulun.
