Numbers 21:26

The armies of Israel now begin to emerge out of the wilderness, and to come into a land inhabited, to enter upon action, and take possession of the frontiers of the land of promise. A glorious campaign this chapter gives us the history of, especially in the latter part of it. Here is, I. The defeat of Arad the Canaanite (Num 21:1-3). II. The chastisement of the people with fiery serpents for their murmurings, and the relief granted them upon their submission by a brazen serpent (Num 21:4-9). III. Several marches forward, and some occurrences by the way (Num 21:10-20). IV. The celebrated conquest of Sihon king of the Amorites (Num 21:21-32), and of Og king of Bashan (Num 21:33-35), and possession taken of their land.

21:26 King Sihon of the Amorites had taken the area north of the Arnon from the Moabites, who earlier controlled it. After Israel occupied this region for several hundred years, it was reclaimed by King Mesha of Moab (see 2 Kgs 3:4-27) through a campaign described in detail around 830 BC on the Mesha Inscription (also known as the Moabite Stone). • Heshbon is usually identified with Tell Hesban, which has not yielded evidence of Late Bronze Age occupation; see study note on Num 21:1.
