Genesis 46:8-15

Now these were the names of the children of Israel, Jacob and his sons, who went to Egypt: Reuben was Jacob’s firstborn. The sons of Reuben were Hanoch, Pallu, Hezron, and Carmi. The sons of Simeon were Jemuel, Jamin, Ohad, Jachin, Zohar, and Shaul, the son of a Canaanite woman. The sons of Levi were Gershon, Kohath, and Merari. The sons of Judah were Er, Onan, Shelah, Perez, and Zerah (but Er and Onan died in the land of Canaan). The sons of Perez were Hezron and Hamul. The sons of Issachar were Tola, Puvah, Job, and Shimron. The sons of Zebulun were Sered, Elon, and Jahleel. These were the sons of Leah, whom she bore to Jacob in Padan Aram, with his daughter Dinah. All the persons, his sons and his daughters, were thirty-three.
