Genesis 10:25-30

Eber had two sons. The first was named Peleg (which means “division”), for during his lifetime the people of the world were divided into different language groups. His brother’s name was Joktan. Joktan was the ancestor of Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab. All these were descendants of Joktan. The territory they occupied extended from Mesha all the way to Sephar in the eastern mountains.
