Source: Nav
Numbers 21:26–30
Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and taken all his land as far as the Arnon. / That is why the poets say: “Come to Heshbon, let it be rebuilt; let the city of Sihon be restored. / For a fire went out from Heshbon, a blaze from the city of Sihon. It consumed Ar of Moab, the rulers of Arnon’s heights.
Isaiah 15:1
This is the burden against Moab: Ar in Moab is ruined, destroyed in a night! Kir in Moab is devastated, destroyed in a night!
