Numbers 21:27-30

Therefore the ballad singers say, “Come to Heshbon, let it be built; let the city of Sihon be established. For fire came out from Heshbon, flame from the city of Sihon. It devoured Ar of Moab, and swallowed the heights of the Arnon. Woe to you, O Moab! You are undone, O people of Chemosh! He has made his sons fugitives, and his daughters captives, to an Amorite king, Sihon. So we overthrew them; Heshbon, as far as Dibon, perished; and we laid waste as far as Nophah; fire spread as far as Medeba.”
