Genesis 10:30

30. Their dwelling was from Mesha In this verse are given the boundaries of the Joktanite Arabs, probably as they existed in the time of Abraham . But it is now impossible to follow them with any degree of certainty . Yet, in the language and monuments of South Arabia there are, as shown above, abundant traces of these thirteen Joktanite tribes . The position of Mesha is uncertain, but it was probably located in North-west Yemen, and the seaport Mousa, on the Red Sea, may be its modern representative . Sepher is undoubtedly the modern Zafar, Dafar, Dhafari, a seaport beneath a lofty mountain on the shore of the Indian Ocean, in Hadhramant, an ancient mart of the Indian trade . These boundaries would fix the primitive seat of the Joktanite Arabs in Yemen and Hadhramant, mostly in Arabia Felix a district stretching from the Nikkum mountains to the Red and Arabian Seas .
