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. Therefore was his name called Levi - לוי levi, joined; because she supposed that, in consequence of all these children, Jacob would become joined to her in as strong affection, at least, as he was to Rachel.
