For there is a fire gone out of Heshbon, a flame from the city of Sihon: it has consumed Ar of Moab, and the lords of the high places of Arnon.
Read Chapter 21

A fire and flame, denote the horrors of war, Judges ix. 20.
Ar. Samaritan and Septuagint read ad, "hath consumed even the country of the Moabites and the lords (or pillars, Septuagint) of Bamoth, (the heights mentioned in ver. 18, 19,) on the Arnon. "These lords may be the principal men, priests, or gods of the city. Jeremias (xlviii. 45,) reads this passage in a different manner, "it (the flame) shall devour part of Moab, and the crown of the head of the children of tumult. "The city of Ar (which some confound with Aroer) always continued in the hands of the Moabites, so that the efforts of Sehon against it, seem to have proved abortive, Deuteronomy ii. 9, 18, 29. (Bonfrere) See chap. xxiv. 17.
