Genesis 29:25-28

In the morning when Jacob saw that he had had sexual relations with Leah, he said to Laban, “What have you done to me? I worked hard for you so that I could marry Rachel! Why did you trick me?” Laban said, “In our country we do not allow the younger daughter to marry before the older daughter. But complete the full week of the marriage ceremony with Leah, and I will give you Rachel to marry also. But you must serve me another seven years.” So Jacob did this, and when he had completed the week with Leah, Laban gave him his daughter Rachel as a wife.
