Genesis 29:27-31

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. When the LORD saw that Leah was unloved, He opened her womb; but Rachel was barren.
