29:33 She became pregnant again and had another son. She said, “Because the Lord heard that I was unloved, he gave me this one too.” So she named him Simeon.

29:34 She became pregnant again and had another son. She said, “Now this time my husband will show me affection, because I have given birth to three sons for him.” That is why he was named Levi.

29:35 She became pregnant again and had another son. She said, “This time I will praise the Lord.” That is why she named him Judah. Then she stopped having children.
