The children of Gad built, i.e; no doubt, they put these places in some habitable and defensible state of repair until they should return. Dibon. Now Dhiban, four miles north of Arnon. It is called Dibon-gad in Numbers 33:45, Numbers 33:46, but it is doubtful whether there is any allusion to its present occupation, since "Gad" was a common affix in the languages of Canaan (cf.
Joshua 11:17). Dibon was subsequently assigned to Reuben (Joshua 13:9), but was recovered by Moab, and became one of his strongholds (of Isaiah 15:2; Jeremiah 48:18, Jeremiah 48:22) The Moabite stone was found here.
Ataroth. Now Attarus, seven miles from Dibon. Aroer. Not the Aroer before Rabbath (Joshua 13:25), but the Aroer by the brink of Arnon (Deuteronomy 2:36; Joshua 13:16).
