Genesis 29:15, 18, 20, 25, 27, 30

Then Laban said to Jacob, “Because you are my kinsman, should you therefore serve me for nothing? Tell me, what shall your wages be?”

Jacob loved Rachel. And he said, “I will serve you seven years for your younger daughter Rachel.”

So Jacob served seven years for Rachel, and they seemed to him but a few days because of the love he had for her.

And in the morning, behold, it was Leah! And Jacob said to Laban, “What is this you have done to me? Did I not serve with you for Rachel? Why then have you deceived me?”

Complete the week of this one, and we will give you the other also in return for serving me another seven years.”

So Jacob went in to Rachel also, and he loved Rachel more than Leah, and served Laban for another seven years.
