Genesis 30:16, 18, 26, 28-29, 32-33

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

And Leah said, God hath given me my hire, because I have given my maiden to my husband: and she called his name Issachar.

Give me my wives and my children, for whom I have served thee, and let me go: for thou knowest my service which I have done thee.

And he said, Appoint me thy wages, and I will give it. And he said unto him, Thou knowest how I have served thee, and how thy cattle was with me.

I will pass through all thy flock to day, removing from thence all the speckled and spotted cattle, and all the brown cattle among the sheep, and the spotted and speckled among the goats: and of such shall be my hire. So shall my righteousness answer for me in time to come, when it shall come for my hire before thy face: every one that is not speckled and spotted among the goats, and brown among the sheep, that shall be counted stolen with me.
