Genesis 10:26

And Joktan begat Almodad, and Sheleph, and Hazar-maveth, and Jerah,

Almodad - the progenitor of an Arab tribe whose name is preserved in Mudad, or El-Mudad; a person famous in Arabian history as chief of the Joktanite tribe Jurhum, in Southeastern Arabia.

Sheleph - [the Saleph of the Greek geographer Ptolemy; the Salfie, or Salafiyeh, of Niebuhr, who describes it Sheleph - [the Saleph of the Greek geographer Ptolemy; the Salfie, or Salafiyeh, of Niebuhr, who describes it as an extensive district of Yemen]. The primeval name has been transmitted by the Arab tribe Beni Sulaf.

Hazormaveth - the court of death: in reference to its unhealthy climate. [Septuagint, ton Sarmooth; Vulgate, Asarmoth; Pliny, Adramitae, or Chadramitae; Ptolemy, Chatramitae-the modern Hadramawt; on the shores of the Indian Ocean.] This tribe has for ages been celebrated, not only for its bold, energetic character, but for its trade-in pursuing which it is favoured by its nearness to the coast and the neighbourhood of the spice-hills of Shichr with the harbours, Cane Emporium and Lyagrum Promontorium, at equal distances from Africa and India.

Jerah, [Septuagint, Iarach]. The settlement of this tribe is probably to be identified with the fortress of Gerakh, in the Nejd.
