And their coast was Jazer,.... Their southern coast; of Jazer, see Nu 21:32; where it is called Jaazer, and is mentioned in Isa 16:8; and in Jer 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, Jos 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 De 2:19 Jud 11:13;unto Aroer that [is] before Rabbath; Aroer was a city of Moab, situated on the river Arnon, Jos 13:9; and stood over against Rabbath, a city of the Amorites, since called Philadelphia, the same that Joab took, 2Sa 12:26; though Reland thinks , that according to the situation of these cities another Aroer must be here meant, and which belonged to the Amorites.
