Numbers 21:26-31

²⁶For Heshbon was the city of Sihon the king of the Amorites; and he had fought against the former king of Moab, and had taken all his land out of his hand, even unto the Arnon.

²⁷Therefore the poets say, Come to Heshbon; let the city of Sihon be built and established.

²⁸For there went forth fire from Heshbon, a flame from the city of Sihon; It consumed Ar of Moab, the lords of the high places of the Arnon.

²⁹Woe to thee, Moab! thou art undone, people of Chemosh: He gave his sons that had escaped, and his daughters into captivity to Sihon the king of the Amorites.

³⁰And we have shot at them; Heshbon is perished even unto Dibon; and we have laid them waste even unto Nophah, which reacheth unto Medeba.

³¹And Israel dwelt in the land of the Amorites.
