Ar

The chief city of Moab, situated along the Arnon River that formed Moab's northern border. God explicitly forbade Israel from attacking Ar because He had given it "to the descendants of Lot" — the Moabites (Deuteronomy 2:9, 18). When Israel passed near it on the way north, the Moabites of Ar sold them food and water (Deuteronomy 2:29). The fragment of the ancient war song quoted in Numbers 21 celebrates Ar's destruction by Sihon the Amorite king before Israel's arrival — fire from Heshbon "devoured Ar of Moab."
