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 should your wages be?”

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

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

So it came to pass 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 you? Why then have you deceived me?”

Fulfill her week, and we will give you this one also for the service which you will serve with me still another seven years.”

Then Jacob also went in to Rachel, and he also loved Rachel more than Leah. And he served with Laban still another seven years.
