Albert Barnes Commentary Numbers 32:34-36

"And the children of Gad built Dibon, and Ataroth, and Aroer, and Atrothshophan, and Jazer, and Jogbehah, and Beth-nimrah, and Beth-haran: fortified cities, and folds for sheep." — Numbers 32:34-36 (ASV)

The cities here named fall into three groups. On Dibon, compare to 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 (that is, “crowns”; Attarus?) was seven miles northwest of Dibon. Aroer (Arair) lay between Dibon and the Arnon.

Atroth, Shophan - was Atroth-Shophan, that is, Atroth, or Ataroth of Shophan, or “of the burrow;” thus distinguished from the Ataroth named in the preceding verse, from which it was probably not far distant. These four cities may be styled the Dibon settlement (Numbers 32:35).

Jaazer - 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) (Numbers 32:36).
