Genesis 29:25-30

25And it came to pass in the morning, that behold, it was Leah. And he said to Laban, What is this thou hast done to me? Have I not served thee for Rachel? Why then hast thou deceived me?

26And Laban said, It is not so done in our place, to give the younger before the firstborn.

27Fulfil the week [with] this one: then we will give thee the other one also, for the service that thou shalt serve me yet seven other years.

28And Jacob did so, and fulfilled the week [with] this one, and he gave him Rachel his daughter to be his wife.

29And Laban gave to Rachel his daughter, Bilhah, his maidservant, to be her maidservant.

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