Genesis 29:25-28

And in the morning, behold, it was Leah! And Jacob said to Laban, “What is this you have done to me? Did I not serve with you for Rachel? Why then have you deceived me?” Laban said, “It is not so done in our country, to give the younger before the firstborn. Complete the week of this one, and we will give you the other also in return for serving me another seven years.” Jacob did so, and completed her week. Then Laban gave him his daughter Rachel to be his wife.
