Genesis 29:28

26And Laban said, It must not be so done in our country, to give the younger before the firstborn.

27Fulfil her week, and we will give thee this also for the service which thou shalt serve with me yet seven other years.

28And Jacob did so, and fulfilled her week: and he gave him Rachel his daughter to wife also.

29And Laban gave to Rachel his daughter Bilhah his handmaid to be her maid.

30And he went in also unto Rachel, and he loved also Rachel more than Leah, and served with him yet seven other years.
