The city that is in the midst of the river; of which see Poole "Deu_3:16", and see Poole "Jos_12:2". Either this is the same city now mentioned, even Aroer, which is said to have been a double city, as the very name seems to import, whereof one part was on the bank of the river, and the other in the middle of it, whence we read of the cities of Aroer, Isa_17:2; or it is another city, possibly Ar, as it is elsewhere named.
Medeba and
Dibon; two cities anciently belonging to the Moabites, and taken from them by the Amorites, Num_21:30, and from them by the Israelites; and after the Israelites were gone into captivity, recovered by the first possessors the Moabites, as may seem from Isa_15:2.
