Genesis 29:32

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

³¹  And when the LORD saw that Leah was hated, he opened her womb: but Rachel was barren.

³²  And Leah conceived, and bare 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.

³³  And she conceived again, and bare a son; and said, Because the LORD hath heard I was hated, he hath therefore given me this son also: and she called his name Simeon.

³⁴  And she conceived again, and bare a son; and said, Now this time will my husband be joined unto me, because I have born him three sons: therefore was his name called Levi.
