Numbers 32:34

The children of Gad built - Aroer - This was situated on the river Arnon, Deuteronomy 2:36; 2 Kings 10:33. It was formerly inhabited by the Emim, a warlike and perhaps gigantic people. They were expelled by the Moabites; the Moabites by the Amorites; and the Amorites by the Israelites. The Gadites then possessed it till the captivity of their tribe, with that of Reuben and the half of the tribe of Manasseh, by the Assyrians, 2 Kings 15:29, after which the Moabites appear to have repossessed it, as they seem to have occupied it in the days of Jeremiah, Jeremiah 48:15-20.

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.

32:34 Built - Repaired and fortified. For they neither had need nor leisure as yet to do more, the old cities not being burnt and ruined, as divers in Canaan were.
