John Wesley on Joshua 13:25

The cities of Gilead - That is, all the cities of eminency; all the cities properly so called, which lay in that part of Gilead; and so this may well agree with ver.31, where half the country of Gilead is said to be given to the Manassites; but there is no mention of any cities there. The land of the children of Ammon - Not of that which was now theirs, for that they were forbidden to meddle with, but of that which was anciently theirs, 'till taken from them by the Amorites, from whom the Israelites took it. Aroer - The border between them and Moab. Rabbah - The chief city of the Ammonites.
