Genesis 29:22-30

And Laban gathered together all the men of the place and made a feast. Now it came to pass in the evening, that he took Leah his daughter and brought her to Jacob; and he went in to her. And Laban gave his maid Zilpah to his daughter Leah as a maid. So it came to pass in the morning, that behold, it was Leah. And he said to Laban, “What is this you have done to me? Was it not for Rachel that I served you? Why then have you deceived me?” And Laban said, “It must not be done so in our country, to give the younger before the firstborn. Fulfill her week, and we will give you this one also for the service which you will serve with me still another seven years.” Then Jacob did so and fulfilled her week. So he gave him his daughter Rachel as wife also. And Laban gave his maid Bilhah to his daughter Rachel as a maid. Then Jacob also went in to Rachel, and he also loved Rachel more than Leah. And he served with Laban still another seven years.
