Gen 29:31-35

31When the Lord saw that Leah was unloved, he opened her womb; but Rachel was barren.32Leah conceived and bore a son, and she named him Reuben; for she said, “Because the Lord has looked on my affliction; surely now my husband will love me.”33She conceived again and bore a son, and said, “Because the Lord has heard that I am hated, he has given me this son also”; and she named him Simeon.34Again she conceived and bore a son, and said, “Now this time my husband will be joined to me, because I have borne him three sons”; therefore he was named Levi.35She conceived again and bore a son, and said, “This time I will praise the Lord”; therefore she named him Judah; then she ceased bearing.
