Sihon king of the Amorites, and Og king of Bashan,.... These are particularly named, because they were the first that were slain, and were the most mighty and powerful; see Deu 3:11. These the Lord slew by the hand of Moses, a type of Christ; who has destroyed the god and prince of this world, that had the power of death, the devil; and has spoiled all his principalities and powers; and all the kingdoms of Canaan; thirty one of them. These words explain the former; as the two kings mentioned point at the mighty kings slain, these kingdoms show who the great nations were that were smitten.
