Genesis 10:21-32

Also to Shem, the father of all the children of Eber, and the older brother of Japheth, children were born. The sons of Shem were Elam and Asshur and Arpachshad and Lud and Aram. The sons of Aram were Uz and Hul and 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 the one was Peleg, for in his days the earth was divided; and his brother’s name was Joktan. Joktan became the father of Almodad and Sheleph and Hazarmaveth and Jerah and Hadoram and Uzal and Diklah and Obal and Abimael and Sheba and Ophir and Havilah and Jobab; all these were the sons of Joktan. Now their settlement extended from Mesha as you go toward Sephar, the hill country of the east. These are the sons of Shem, according to their families, according to their languages, by their lands, according to their nations. These are the families of the sons of Noah, according to their genealogies, by their nations; and out of these the nations were separated on the earth after the flood.
