Deuteronomy 2:36

“From Aroer, which is by the brink of the river Arnon etc.] Upon the border of Moab, and the principal city of it; (see <244819>Jeremiah 48:19) and from the city that is by the river; or even the city that is in the midst of the river, the city Aroer, which seems to be meant; (see <061202>Joshua 12:2 13:9). This river is afterwards called the river of Gad, (<102405>2 Samuel 24:5) in the midst of it Aroer was, perhaps because it was possessed by the tribe of Gad: even unto Gilead; Mount Gilead and the country adjacent to it, which belonged to Og king of Bashan: there was not one city too strong for us; that could hold out against them, when attacked and besieged by them, but presently…”

“Aroer: Deu 3:12, Deu 4:48; Jos 13:9; Isa 17:2; Jer 48:19 not: Jos 1:5; Psa 44:3; Isa 41:15, Isa 41:16; Rom 8:31 Deuteronomy 2:37”
