Joshua 13:9

From Aroer, that is on the bank of the river Arnon ,.... A city belonging to Moab, from whence the description begins, the river Arnon, on which it was situated, being the border between Moab and the Amorites, Numbers 21:13 ,

and the city that is in the midst of the river ; or "even the city"; meaning the same city of Aroer, it lying both on the bank of it, and in the middle of it, or it was a double city, as may seem from Isaiah 17:2 ; and so differently situated at that river:

and all the plains of Medeba unto Dibon ; of these two places, see Numbers 21:30 ; between them lay a plain, which some take to be the plain of Moab; but it rather seems to be a plain that was between these two places, and, according to Joshua 13:17 , Dibon itself was in a plain.
