Numbers 21:27-31

²⁷Therefore those who speak in proverbs say, “Come to Heshbon. Let the city of Sihon be built and established;

²⁸for a fire has gone out of Heshbon, a flame from the city of Sihon. It has devoured Ar of Moab, The lords of the high places of the Arnon.

²⁹Woe to you, Moab! You are undone, people of Chemosh! He has given his sons as fugitives, and his daughters into captivity, to Sihon king of the Amorites.

³⁰We have shot at them. Heshbon has perished even to Dibon. We have laid waste even to Nophah, Which reaches to Medeba.”

³¹Thus Israel lived in the land of the Amorites.
