Isaiah 21:7

What the man upon the watch-tower sees first of all, is a long, long procession, viz., the hostile army advancing quietly, like a caravan, in serried ranks, and with the most perfect self-reliance. "And he saw a procession of cavalry, pairs of horsemen, a procession of asses, a procession of camels; and listened sharply, as sharply as he could listen." Receb, both here and in Isa 21:9, signifies neither riding-animals nor war-chariots, but a troop seated upon animals - a procession of riders. In front there was a procession of riders arranged two and two, for Persians and Medes fought either on foot or on horseback (the latter, at any rate, from the time of Cyrus; vid., Cyrop. iv 3); and pârâsh signifies a rider on horseback (in Arabic it is used in distinction from râkib, the rider on camels). Then came lines of asses and camels, a large number of which were always taken with the Persian army for different purposes. They not only carried baggage and provisions, but were taken into battle to throw the enemy into confusion. Thus Cyrus gained the victory over the Lydians by means of the great number of his camels (Herod. i. 80), and Darius Hystaspis the victory over the Scythians by means of the number of asses that he employed (Herod. iv 129). Some of the subject tribes rode upon asses and camels instead of horses: the Arabs rode upon camels in the army of Xerxes, and the Caramanians rode upon asses. What the spy saw was therefore, no doubt, the Persian army. But he only saw and listened. It was indeed "listening, greatness of listening," i.e., he stretched his ear to the utmost (rab is a substantive, as in Isa 63:7; Psa 145:7; and hikshib, according to its radical notion, signifies to stiffen, viz., the ear); (Note: Bttcher has very correctly compared kâshab (kasuba…

In this chapter we have a prophecy of sad times coming, and heavy burdens, I. Upon Babylon, here called "the desert of the sea," that it should be destroyed by the Medes and Persians with a terrible destruction, which yet God's people should have advantage by (Isa 21:1-10). II. Upon Dumah, or Idumea (Isa 21:11, Isa 21:12). III. Upon Arabia, or Kedar, the desolation of which country was very near (Isa 21:13-17). These and other nations which the princes and people of Israel had so much to do with the prophets of Israel could not but have something to say to. Foreign affairs must be taken notice of as well as domestic ones, and news from abroad enquired after as well as news at home.

21:7 The riders were messengers who reported what had taken place on the battlefield.
