Numbers 21:27-30

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.
