Genesis 10:25-30

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. 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.
