Arabia was a large country, that lay eastward and southward of the land of Canaan. Much of it was possessed by the posterity of Abraham. The Dedanim, here mentioned (v. 13), descended from Dedan, Abraham's son by Keturah; the inhabitants of Tema and Kedar descended from Ishmael, Gen. xxv. 3, 13, 15. The Arabians generally lived in tents, and kept cattle, were a hardy people, inured to labour; probably the Jews depended upon them as a sort of a wall between them and the more warlike eastern nations; and therefore, to alarm them, they shall hear the burden of Arabia, and see it sinking under its own burden.
