      Probably in the wars between Assyria and Egypt; Idumea and Arabia lay somewhat on the intermediate line of march.

      13. upon--that is, respecting.
      forest--not a grove of trees, but a region of thick underwood, rugged and inaccessible; for Arabia has no forest of trees.
      travelling companies--caravans: ye shall be driven through fear of the foe to unfrequented routes (Isa 33:8; Jud 5:6; Jer 49:8 is parallel to this passage).
      Dedanim--In North Arabia (Ge 25:3; Jer 25:23; Eze 25:13; 27:20; a different "Dedan" occurs Ge 10:7).
