Genesis 29:22-30

And Laban gathered together all the men of the place, and made a feast. And it came to pass in the evening, that he took Leah his daughter, and brought her to him; and he went in unto her. And Laban gave Zilpah his handmaid unto his daughter Leah for a handmaid. And it came to pass in the morning that, behold, it was Leah: and he said to Laban, What is this thou hast done unto me? did not I serve with thee for Rachel? wherefore then hast thou beguiled me? And Laban said, It is not so done in our place, to give the younger before the first-born. Fulfil the week of this one, and we will give thee the other also for the service which thou shalt serve with me yet seven other years. And Jacob did so, and fulfilled her week: and he gave him Rachel his daughter to wife. And Laban gave to Rachel his daughter Bilhah his handmaid to be her handmaid. And he went in also unto Rachel, and he loved also Rachel more than Leah, and served with him yet seven other years.
