And Leah conceived and gave birth to a son, and she named him Reuben, for she said, “The LORD has seen my affliction. Surely my husband will love me now.” Again 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. 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. And once more she conceived and gave birth to a son and said, “This time I will praise the LORD.” So she named him Judah. Then Leah stopped having children.
Then Leah said, “God has rewarded me for giving my maidservant to my husband.” So she named him Issachar. Again Leah conceived and bore a sixth son to Jacob. “God has given me a good gift,” she said. “This time my husband will honor me, because I have borne him six sons.” And she named him Zebulun.
Now these are the names of the sons of Israel (Jacob and his descendants) who went to Egypt: Reuben, Jacob’s firstborn. The sons of Reuben: Hanoch, Pallu, Hezron, and Carmi. The sons of Simeon: Jemuel, Jamin, Ohad, Jachin, Zohar, and Shaul the son of a Canaanite woman. The sons of Levi: Gershon, Kohath, and Merari. The sons of Judah: Er, Onan, Shelah, Perez, and Zerah; but Er and Onan died in the land of Canaan. The sons of Perez: Hezron and Hamul. The sons of Issachar: Tola, Puvah, Job, and Shimron. The sons of Zebulun: Sered, Elon, and Jahleel. These are the sons of Leah born to Jacob in Paddan-aram, in addition to his daughter Dinah. The total number of sons and daughters was thirty-three.
