Genesis 10:28-32

Obal, Abimael, Sheba,

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

Now their settlement extended from Mesha going toward Sephar, the hill country of the east.

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

These are the families of the sons of Noah, according to their descendants, by their nations; and out of these the nations were separated on the earth after the flood.
