Josephus said, "Sabathes [Sabtah] founded the Sabathens—they are now called by the Greeks, Astaborans." One thing Josephus shows is that they kept their name, A-stab-orans. The Blue Nile, in Ethiopia, was known anciently as the Astasobas. Sabtah may have founded Shabna (also spelt Sabota), the ancient capital of Hadhramaut. There was also the province of Saba of southern Arabia and were undoubtedly related to the Sabaeans of Yemen. Ptolemy's map mentions a place in the Sudan, along the southern parts of the White Nile as Sube, a likely derivation from Saba as does Strabo. He places "Ethiopia" in northern Sudan where the Cushites lived for a time. It is this region in northern Sudan which was known as Kush to the Egyptians of old. In addition, Josephus also records the name of Sabtah's descendants as the Sabateni. Ptolemy knew them as the Stabæi, and Pliny called them the Messabathi.
Nearby lies the land of the Somalis. To this day, the two largest Somali clan groups are the Somaal and the Sab. The Somaal are primarily nomadic shepherds. The Sab usually settle in communities and live as farmers or craftsmen. The Sab also dwell in Northern Ethiopia. Perhaps the tribes that left for Asia took the name Asta from Astaborans with them as a town called Asta existed in the Indian archipelago of old. There was also a tribe of people by the name of Astacorni in India according to Strabo, and a district of Borneo is still known as Sabah. These are all linguistically akin to Sabtah or his brother, Sabteca.
