Genesis 29:21-35 NASB
Then Jacob said to Laban, “Give me my wife, for my time is completed, that I may go in to her.” Laban gathered all the men of the place and made a feast. Now in the evening he took his daughter Leah, and brought her to him; and Jacob went in to her. Laban also gave his maid Zilpah to his daughter Leah as a maid. So it came about 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 with you? Why then have you deceived me?” But Laban said, “It is not the practice in our place to marry off the younger before the firstborn. Complete the week of this one, and we will give you the other also for the service which you shall serve with me for another seven years.” Jacob did so and completed her week, and he gave him his daughter Rachel as his wife. Laban also gave his maid Bilhah to his daughter Rachel as her maid. So Jacob went in to Rachel also, and indeed he loved Rachel more than Leah, and he served with Laban for another seven years.
Now the LORD saw that Leah was unloved, and He opened her womb, but Rachel was barren. Leah conceived and bore a son and named him Reuben, for she said, “Because the LORD has seen my affliction; surely now my husband will love me.” Then she conceived again and bore a son and said, “Because the LORD has heard that I am unloved, He has therefore given me this son also.” So she named him Simeon. She conceived again and bore a son and said, “Now this time my husband will become attached to me, because I have borne him three sons.” Therefore he was named Levi. And she conceived again and bore a son and said, “This time I will praise the LORD.” Therefore she named him Judah. Then she stopped bearing.
