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.

The desire, good in itself, but often too great and irregular, of being the mother of the promised Seed, with the honour of having many children, and the reproach of being barren, were causes of this unbecoming contest between the sisters.
