Numbers 21:34 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.
[Patriarchs & Prophets pp 436] When the Hebrews looked upon the lofty form of that giant of giants towering above the soldiers of his army; when they saw the hosts that surrounded him, and beheld the seemingly impregnable fortress, behind which unseen thousands were entrenched, the hearts of many in Israel quaked with fear. But Moses was calm and firm; the Lord had said concerning the king of Bashan, “Fear him not:
For I will deliver him, and all his people, and his land, into thy hand; and thou shalt do unto him as thou didst unto Sihon king of the Amorites, which dwelt at Heshbon.” The calm faith of their leader inspired the people with confidence in God. They trusted all to His omnipotent arm, and He did not fail them. Not mighty giants nor walled cities, armed hosts nor rocky fortresses, could stand before the Captain of the Lord's host. The Lord led the army; the Lord discomfited the enemy; the Lord conquered in behalf of Israel.
The giant king and his army were destroyed, and the Israelites soon took possession of the whole country. Thus was blotted from the earth that strange people who had given themselves up to iniquity and abominable idolatry. In the conquest of Gilead and Bashan there were many who recalled the events which nearly forty years before had, in Kadesh, doomed Israel to the long desert wandering. They saw that the report of the spies concerning the Promised Land was in many respects correct.
Numbers 21:35 So they smote him, and his sons, and all his people, until there was none left him alive: and they possessed his land.
May The Lord add His blessing to the study of His word. God bless!
