Genesis 10:21-31

Shem's descendants had their own languages, tribes, and land. He was the elder brother of Japheth and the ancestor of the tribes of Eber. Shem was the ancestor of Elam, Asshur, Arpachshad, Lud, and Aram. Aram was the ancestor of Uz, Hul, Gether, and Mash. Arpachshad was the father of Shelah and the grandfather of Eber, whose first son was named Peleg, because it was during his time that tribes divided up the earth. Eber's second son was Joktan. Joktan was the ancestor of Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab. Their land reached from Mesha in the direction of Sephar, the hill country in the east.
