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

Then Laban said to Jacob, “You are my relative, but it is not right for you to work for me without pay. What would you like me to pay you?”

Jacob loved Rachel, so he said to Laban, “Let me marry your younger daughter Rachel. If you will, I will work seven years for you.”

So Jacob worked for Laban seven years so he could marry Rachel. But they seemed like just a few days to him because he loved Rachel very much.

In the morning when Jacob saw that he had had sexual relations with Leah, he said to Laban, “What have you done to me? I worked hard for you so that I could marry Rachel! Why did you trick me?”

But complete the full week of the marriage ceremony with Leah, and I will give you Rachel to marry also. But you must serve me another seven years.”

So Jacob had sexual relations with Rachel also, and Jacob loved Rachel more than Leah. Jacob worked for Laban for another seven years.
