Genesis 10:21-30

And unto Shem, the father of all the children of Eber, the elder brother of Japheth, to him also were children born. The sons of Shem: Elam, and Asshur, and Arpachshad, and Lud, and Aram. And the sons of Aram: Uz, and Hul, and Gether, and Mash. And Arpachshad begat Shelah; and Shelah begat Eber. And unto Eber were born two sons: the name of the one was Peleg; for in his days was the earth divided; and his brother’s name was Joktan. And Joktan begat 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. And their dwelling was from Mesha, as thou goest toward Sephar, the mountain of the east.
