Genesis 30:14

11 And Leah said, Fortunate! and she called his name Gad.

12 And Zilpah Leah`s handmaid bare Jacob a second son.

13 And Leah said, Happy am I! for the daughters will call me happy: 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 away 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.

16 And Jacob came from the field in the evening, and Leah went out to meet him, and said, Thou must come in unto me; for I have surely hired thee with my son`s mandrakes. And he lay with her that night.

17 And God hearkened unto Leah, and she conceived, and bare Jacob a fifth son.
