Numbers 21:26-29

26Heshbon had been the capital of King Sihon of the Amorites. He had defeated a former Moabite king and seized all his land as far as the Arnon River.

27Therefore, the ancient poets wrote this about him: “Come to Heshbon and let it be rebuilt! Let the city of Sihon be restored.

28A fire flamed forth from Heshbon, a blaze from the city of Sihon. It burned the city of Ar in Moab; it destroyed the rulers of the Arnon heights.

29What sorrow awaits you, O people of Moab! You are finished, O worshipers of Chemosh! Chemosh has left his sons as refugees, his daughters as captives of Sihon, the Amorite king.
