Numbers 21:29

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.
