For fire went out from Heshbon, a flame from the city of Sihon; it consumed Ar of Moab, the lords of the heights of the Arnon.
In context
26For Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and taken all his land out of his hand, as far as the Arnon. 27That is why the poets say: “Come to Heshbon — let it be built, let the city of Sihon be established. 28For fire went out from Heshbon, a flame from the city of Sihon; it consumed Ar of Moab, the lords of the heights of the Arnon. 29Woe to you, Moab! You are destroyed, people of Chemosh! He has made his sons fugitives and his daughters captives, to Sihon king of the Amorites. 30We shot them down; Heshbon is destroyed as far as Dibon. We laid waste as far as Nophah, which reaches to Medeba.”
