Genesis 30:12

9 When Leah saw that she had finished bearing, she took Zilpah, her handmaid, and gave her to Jacob as a wife.

10 Zilpah, Leah`s handmaid, bore Jacob a son.

11 Leah said, "How fortunate!" She named him Gad.

12 Zilpah, Leah`s handmaid, bore Jacob a second son.

13 Leah said, "Happy am I, for the daughters will call me happy." She named him Asher.

14 Reuben went in the days of wheat harvest, 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."

15 She said to her, "Is it a small matter that you have taken away my husband? Would you take away my son`s mandrakes, also?" Rachel said, "Therefore he will lie with you tonight for your son`s mandrakes."
