Genesis 29:34

Once again Leah conceived and gave birth to a son, and she said, “Now at last my husband will become attached to me, because I have borne him three sons.” So he was named Levi.

Note Levi sounds like the Hebrew for being attached to or feeling affection for.

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.

Note Levi: that is, Joined

She conceived again, and bore a son. She said, “Now this time my husband will be joined to me, because I have borne him three sons.” Therefore his name was called Levi.

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