Genesis 29:30-34

30And he went in also to Rachel, and he loved also Rachel more than Leah, and served with him yet seven other years.

31And when the LORD saw that Leah was hated, he opened her womb: but Rachel was barren. 32And Leah conceived, and bore a son, and she called his name Reuben: for she said, Surely the LORD hath looked upon my affliction; now therefore my husband will love me.1 33And she conceived again, and bore a son; and said, Because the LORD hath heard that I was hated, he hath therefore given me this son also: and she called his name Simeon.2 34And she conceived again, and bore a son; and said, Now this time will my husband love me, because I have borne him three sons: therefore was his name called Levi.3
