33Again she conceived and gave birth to a son, and she said, “Because the LORD has heard that I am unloved, He has given me this son as well.” So she named him Simeon.
34Once 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.
