And their coast was Jazer
Their southern coast; of Jazer, see ( Numbers 21:32 ) ; where it is called Jaazer, and is mentioned in ( Isaiah 16:8 ) ; and in ( Jeremiah 48:32 ) , where it is spoken of as a city of Moab, as it was in the days of those prophets:
and all the cities of Gilead;
which lay in those parts, for the whole was not given to this tribe, half of Gilead was given to the half tribe of Manasseh, ( Joshua 13:31 ) ;
and half the land of the children of Ammon;
not what then belonged to them, but what had been taken from them by the Amorites; and which Israel taking from them, had a right to retain, though they were forbid meddling with any of their land in present possession; see ( Deuteronomy 2:19 ) ( Judges 11:13-24 ) ;
unto Aroer that [is] before Rabbath;
Aroer was a city of Moab, situated on the river Arnon, ( Joshua 13:9 ) ; and stood over against Rabbath, a city of the Amorites, since called Philadelphia, the same that Joab took, ( 2 Samuel 12:26 ) ; though Reland thinks F14, that according to the situation of these cities another Aroer must be here meant, and which belonged to the Amorites.
