Numbers 21:27-31

²⁷That is why those who speak in proverbs say, “Come to Heshbon. Let the city of Sihon be rebuilt and established again.

²⁸A fire blazed from Heshbon, a flame from the city of Sihon that devoured Ar of Moab, and the owners of the high places of Arnon.

²⁹Woe to you, Moab! You have perished, people of Chemosh. He has made his sons to be fugitives and his daughters to be prisoners of Sihon king of the Amorites.

³⁰But we have conquered Sihon. Heshbon is devastated all the way to Dibon. We have defeated them all the way to Nophah, which reaches to Medeba.”

³¹So Israel began to live in the Amorites' land.
