Genesis 10:21-30

Also to Shem, the father of all the children of Eber [including the Hebrews], the older brother of Japheth, children were born. The sons of Shem: Elam, Asshur, Arpachshad, Lud and Aram; the sons of Aram [ancestor of the Syrians]: Uz, Hul, Gether and Mash. Arpachshad became the father of Shelah; and Shelah became the father of Eber. Two sons were born to Eber; the name of one was Peleg (division), for [the inhabitants of] the earth were divided in his days; and his brother’s name was Joktan. Joktan became the father of Almodad, Sheleph, Hazarmaveth, Jerah, and Hadoram, Uzal, Diklah, and Obal, Abimael, Sheba, and Ophir, Havilah, and Jobab; all these were the sons of Joktan. Now their territory extended from Mesha as one goes toward Sephar, to the hill country of the east.
