These are their generations--the heads of his twelve tribes. The great northern desert of Arabia, including the entire neck, was colonized by these tribes; and if we can recover, in the modern geography of this part of the country, Arab tribes bearing the names of those patriarchs, that is, names corresponding with those preserved in the original catalogue of Scripture, we obtain at once so many evidences, not of mere similarity, but of absolute identification [FORSTER].

sons of Keturah--These became founders of nomadic tribes in the north of Arabia and Syria, as Midian of the Midianites (Gen 36:35; Jdg 6:2).

But it is unnecessary to mention any more of these obscure nomads, except to notice that Jobab (Ch1 1:44), one of the kings of Edom, is considered to be Job, and that his seat was in the royal city of Dinahab (Gen 36:32; Ch1 1:43), identified with O'Daeb, a well-known town in the center of Al Dahna, a great northern desert in the direction of Chaldea and the Euphrates [FORSTER].
