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

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

Now Jacob loved Rachel, so 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 his love for her.

So it came about in the morning that, behold, it was Leah! And he said to Laban, “What is this you have done to me? Was it not for Rachel that I served with you? Why then have you deceived me?”

Complete the week of this one, and we will give you the other also for the service which you shall serve with me for another seven years.”

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