Isaiah 17:2

The cities of Aroer are forsaken
The inhabitants of them being slain, or carried captive, or obliged to flee. Aroer was a city by the river Arnon, on the borders of Moab and Ammon, ( Deuteronomy 2:36 ) ( Deuteronomy 3:12 ) , it was originally in the hands of the Amorites, and sometimes in the hands of the Moabites and Ammonites: it was given by Moses to the Reubenites and, Gadites, from whom it was taken by the Syrians, and in whose possession it seems to have been at this time; see ( 2 Kings 10:33 ) though Jarchi thinks it was now in the hands of Pekah king of Israel, and said to be forsaken, because the Reubenites and Gadites were now carried captive. Jerom ^F13 says it was seen in his time, upon the top of the mountain. Here it seems to designs a country of this name, in which were many cities. Grotius thinks it was a tract of land in Syria, the same with the Aveira of Ptolemy ^F14. Vitringa is of opinion that Damascus itself is meant, which was a double city, like that divided by the river Chrysorrhoas, as this was by Arnon. They shall be for flocks which shall lie down;
instead of houses, there should be sheepcotes and shepherds' tents, and instead of men, sheep; and where streets were, grass would grow, and flocks feed and lie down; which is expressive of the utter desolation of these cities, or this tract of ground: and none shall make [them] afraid;
the flocks of sheep, timorous creatures, easily frightened; but so great should be the depopulation now, there would be no man upon the spot, or any pass by, to give them any disturbance.
