Genesis 10:25-30

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.
