For fire went out from Heshbon, a flame from the city of Sihon. It has consumed Ar of Moab and the lords ¹  of the high places of Arnon.

When Balak heard that Balaam was coming, he went out to meet him at a city of Moab which was on the border of the Arnon at the boundary of his territory.

For Heshbon was the city of King Sihon of the Amorites. Now he had fought against the former king of Moab and had taken all of his land from his control, ¹  as far as the Arnon.
