Genesis 10:21-30

Sons were also born to Shem, whose older brother was Japheth; Shem was the ancestor of all the sons of Eber. The sons of Shem: Elam, Ashur, Arphaxad, Lud and Aram. The sons of Aram: Uz, Hul, Gether and Meshek. Arphaxad was the father of Shelah, and Shelah the father of Eber. Two sons were born to Eber: One was named Peleg, because in his time the earth was divided; his brother was named Joktan. Joktan was the father of Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah and Jobab. All these were sons of Joktan. The region where they lived stretched from Mesha toward Sephar, in the eastern hill country.
