Num 21:27-28
The glorious conquest and destruction of the capital of the powerful king of the Amorites, in the might of the Lord their God, inspired certain composers of proverbs (משׁלים denom. from משׁל) to write songs in commemoration of the victory. Three strophes are given from a song of this kind, and introduced with the words “therefore,' sc., because Heshbon had fallen in this manner, “the composers of proverbs say.” The first strophe (Num 21:27 and Num 21:28) runs thus: “Come to Heshbon: Built and restored be the city of Sihon! For fire went out of Heshbon; flames from the city of Sihon. It devoured Ar Moab, the lords of the heights of Arnon.” The summons to come to Heshbon and build this ruined city up again, was not addressed to the Israelites, but to the conquered Amorites, and is to be interpreted as ironical (F. v. Meyer; Ewald, Gesch. ii. pp. 267, 268): “Come to Heshbon, ye victorious Amorites, and build your royal city up again, which we have laid in ruins! A fire has gone out of it, and burned up Ar Moab, and the lords of the heights of the Arnon.” The reference is to the war-fire, which the victorious Amorites kindled from Heshbon in the land of Moab under the former king of Moab; that is to say, the war in which they subjugated Ar Moab and the possessors of the heights of Arnon. Ar Moab (see at Num 21:15) appears to have been formerly the capital of all Moabitis, or at least of that portion of it which was situated upon the northern side of the Arnon; and the prominence given to it in Deu 2:9, Deu 2:18, Deu 2:29, is in harmony with this. The heights of Arnon are mentioned as the limits to which Sihon had carried his victorious supremacy over Moab. The “lords” of these heights are the Moabites.
