Genesis 46:11-15

And the sons of Levi; Gershon, Kohath, and Merari.

And the sons of Judah; Er, and Onan, and Shelah, and Pharez, and Zerah: but Er and Onan died in the land of Canaan. And the sons of Pharez were Hezron and Hamul.

And the sons of Issachar; Tola, and Phuvah, and Job, and Shimron.

And the sons of Zebulun; Sered, and Elon, and Jahleel.

These be the sons of Leah, which she bare unto Jacob in Padan-aram, with his daughter Dinah: all the souls of his sons and his daughters were thirty and three.
