To Eber were born two sons: the name of the one was Peleg, for in his days the earth was divided, and his brother’s name was Joktan [pronounced “Yok-tan”]. Joktan fathered Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab; all these were the sons of Joktan. The territory in which they lived extended from Mesha in the direction of Sephar to the hill country of the east.
