The same observation meets us, concerning the king of Bashan and his courts, as the king of the Amorites and his. The victories of Israel were all of covenant engagements, and all accomplished by the LORD GOD of Israel, in confirmation of covenant promises. But what these things were in history, have been and will be spiritually accomplished for the LORD'S people, in the conquest of that country for the redeemed of the LORD, of which Canaan was but a type. And as Israel of old sung their song of triumph for the same, so may Israel now. To him which led his people through the wilderness, who smote Sihon, king of the Amorites, and Og, the king of Bashan; "for his mercy endureth forever." Psalms 136:16-20.
Numbers 21:31-35
31 Thus Israel dwelt in the land of the Amorites.
32 And Moses sent to spy out Jaazer, and they took the villages thereof, and drove out the Amorites that were there.
33 And they turned and went up by the way of Bashan: and Og the king of Bashan went out against them, he, and all his people, to the battle at Edrei.
34 And the LORD said unto Moses, Fear him not: for I have delivered him into thy hand, and all his people, and his land; and thou shalt do to him as thou didst unto Sihon king of the Amorites, which dwelt at Heshbon.
35 So they smote him, and his sons, and all his people, until there was none left him alive: and they possessed his land.
