Sabtah Sabta
From BiblePortal Wikipedia
Hastings' Dictionary of the Bible [1]
SABTA, Sabtah . In the genealogical list of Genesis 10:7 a son of Cush, named between Havilah and other Arabian districts. It was probably a region on or near the east coast of Arabia, but in spite of several conjectures it has not been identified with any historical tribe or country. The relationship with Cush is to be accounted for on the ground that the Cushites were held to have extended across the Red Sea from Nubia north-eastward over the great peninsula.
