Genesis 29:16-20

Now Laban had two daughters; the name of the older was Leah, and the name of the younger was Rachel. Leah’s eyes were weak, but Rachel was beautiful in form and appearance. Jacob loved Rachel, so he said, “I will serve you [as a hired workman] for seven years [in return] for [the privilege of marrying] Rachel your younger daughter.” Laban said, “It is better that I give her [in marriage] to you than give her to another man. Stay and work with me.” So Jacob served [Laban] for seven years for [the right to marry] Rachel, but they seemed like only a few days to him because of his love for her.
