Genesis 30:12

9 When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.

10 And Zilpah Leah's maid bare Jacob a son.

11 And Leah said, A troop cometh: and she called his name Gad.

12 And Zilpah Leah's maid bare Jacob a second son.

13 And Leah said, Happy am I, for the daughters will call me blessed: and she called his name Asher.

14 And Reuben went in the days of wheat harvest, and found mandrakes in the field, and brought them unto his mother Leah. Then Rachel said to Leah, Give me, I pray thee, of thy son's mandrakes.

15 And she said unto her, Is it a small matter that thou hast taken my husband? and wouldest thou take away my son's mandrakes also? And Rachel said, Therefore he shall lie with thee to night for thy son's mandrakes.
