Genesis 29:19-20, 30

Laban said, “It would be better for her to marry you than someone else, so stay here with me.” 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.

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