Genesis 10:21-30

Shem, the older brother of Japheth, also had sons and was the ancestor of all the sons of Eber, who were also known as “Hebrews.” The sons of Shem were Elam, Assyria, Arphaxad, Lud, and Aram. The sons of Aram were Uz, Hul, Gether, and Mash. Arphaxad was the father of Shelah, the father of Eber. Eber was the father of two sons: Peleg, (or “Division,” for during his lifetime the earth was divided), and his brother Joktan, the father of Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab. All the descendants of Joktan lived in the territory that extends all the way from Mesha toward the eastern hills of Sephar.
