with the Ammonites—FAIRBAIRN explains and translates, "upon the children of Ammon" (elliptically for, "I will open Moab to the men of the east, who, having overrun the children of Ammon, shall then fall on Moab"). MAURER, as English Version, "with the Ammonites," that is, Moab, "together with the land of Ammon," is to be thrown "open to the men of the east," to enter and take possession (Jer. 49:1-39).
open . . . from the cities—I will open up the side, or border of Moab (metaphor from a man whose side is open to blows), from the (direction of) the cities on his northwest border beyond the Arnon, once assigned to Reuben (Joshua 13:15-21), but now in the hands of their original owners; and the "men of the east," the wandering Bedouin hordes, shall enter through these cities into Moab and waste it. Moab accordingly was so wasted by them, that long before the time of Christ it had melted away among the hordes of the desert. For "cities," GROTIUS translates the Hebrew as proper names, the Ar and Aroer, on the Arnon. Hence the Hebrew for "cities," "Ar" is repeated twice (Numbers 21:28; Deuteronomy 2:36; Isaiah 15:1).
glory of the country—The region of Moab was richer than that of Ammon; it answers to the modern Belka, the richest district in South Syria, and the scene in consequence of many a contest among the Bedouins. Hence it is called here a "glorious land" (literally, "a glory," or "ornament of a land") [FAIRBAIRN]. Rather, "the glory of the country" is in apposition with "cities" which immediately precedes, and the names of which presently follow.
Beth-jeshimoth—meaning "the city of desolations"; perhaps so named from some siege it sustained; it was towards the west.
Baal-meon—called also "Beth-meon" (Jeremiah 48:23), and "Beth-baal-meon" (Joshua 13:17, called so from the worship of Baal), and "Bajith," simply (Isaiah 15:2).
Kiriathaim—"the double city." The strength of these cities engendered "the pride" of Moab (Isaiah 16:6).
