John Gill's Bible Commentary Ver. 8. And we took at that time out of the hands of the two kings of the Amorites , etc.] Sihon king of Heshbon, and Og king of Bashan; the land that [was] on this side Jordan ; where Moses then was, being in the plains of Moab, and was the country beyond Jordan, with respect to the land of Canaan, and when in that: from the river of Arnon unto Mount Hermon ; Arnon was a river which divided Moab and the Amorites, ( Numbers 22:13) and Hermon was a mountain of Gilead, which ended where Lebanon began, and was the northerly border of this country. It was remarkable for the dew that fell on it; (see Gill on “ <19D303> Psalm 133:3”).
Matthew Henry Commentary
Verses 1-11 - Og was very powerful, but he did not take warning by the ruin of Sihon and desire conditions of peace. He trusted his own strength, and so wa hardened to his destruction. Those not awakened by the judgments of God on others, ripen for the like judgments on themselves.
