John Gill Bible Commentary

And I will make Rabbath a stable for camels,.... Creatures much used by the eastern nations, especially the Arabians; who pitching their tents about Rabbath, the royal city, the metropolis of the children of Ammon, would convert the houses, and even palaces in it, into stables for their camels. This city, in Jerom's time, as he says, was called Philadelphia, from Ptolemy Philadelphus, who rebuilt it. And the Ammonites a couching place for flocks; that is, the land of the Ammonites should be made a place for flocks of sheep to lie down in, which the Arabians would bring and feed upon it: and ye shall know that I am the Lord; omniscient, and sees and observes all your insults upon the children of Israel and Judah; and omnipotent, able to perform all that is threatened; and immutable, bringing about all that is here prophesied of.
