Numbers 21:26-28

Young's Literal Translation

²⁶ for Heshbon is a city of Sihon king of the Amorite, and he hath fought against the former king of Moab, and taketh all his land out of his hand, unto Arnon;

²⁷ therefore those using similes say -- `Enter ye Heshbon, Let the city of Sihon be built and ready,

²⁸ For fire hath gone out from Heshbon, A flame from the city of Sihon, It hath consumed Ar of Moab, Owners of the high places of Arnon.
