The cities here named fall into three groups. On Dibon, compare Numbers 21:19. The Moabite stone was discovered here in 1868. This city, occupied on the first acquisition of the territory by the Gadites, and assigned by Joshua to the Reubenites, was eventually recaptured by the Moabites, in whose hands it remained. Ataroth, i. e., “crowns” (Attarus?) was seven miles northwest of Dibon. Aroer (Arair) lay between Dibon and the Arnon.
Atroth, Shophan - , was Atroth-Shophan, i. e., Atroth, or Ataroth of Shophan, or “of the burrow;” thus distinguished from the Ataroth named in the verse preceding from which it was probably not far distant. These four cities may be styled the Dibon settlement.
Jaazer - (compare Numbers 32:1) with the neighboring “Jogbehah” (Jebeiha), seven miles to the northeast, formed the second group.
The third Gadite settlement lay in the valley of the Jordan, to the west of the preceding. It comprised the cities of Bethnimrah (Nimrun) and “Beth-haran” (Beit-ha-ran).
