Genesis 10:28

To Eber were born two sons. The name of the one was Peleg, for in his days the earth was divided. His brother’s name was Joktan.

Joktan became the father of Almodad, Sheleph, Hazarmaveth, Jerah,

Hadoram, Uzal, Diklah,

Ophir, Havilah, and Jobab. All these were the sons of Joktan.

Their dwelling extended from Mesha, as you go toward Sephar, the mountain of the east.

These are the sons of Shem, by their families, according to their languages, lands, and nations.
