The utter destruction of the people of Jericho was but a fulfillment of the commands previously given through Moses concerning the inhabitants of Canaan: “Thou shalt smite them, and utterly destroy them.” Deuteronomy 7:2. “Of the cities of these people, ... thou shalt save alive nothing that breatheth.” Deuteronomy 20:16. To many these commands seem to be contrary to the spirit of love and mercy enjoined in other portions of the Bible, but they were in truth the dictates of infinite wisdom and goodness. God was about to establish Israel in Canaan, to develop among them a nation and government that should be a manifestation of His kingdom upon the earth. They were not only to be inheritors of the true religion, but to disseminate its principles throughout the world. The Canaanites had abandoned themselves to the foulest and most debasing heathenism, and it was necessary that the land should be cleared of what would so surely prevent the fulfillment of God’s gracious purposes.

The inhabitants of Canaan had been granted ample opportunity for repentance. Forty years before, the opening of the Red Sea and the judgments upon Egypt had testified to the supreme power of the God of Israel. And now the overthrow of the kings of Midian, of Gilead and Bashan, had further shown that Jehovah was above all gods. The holiness of His character and His abhorrence of impurity had been evinced in the judgments visited upon Israel for their participation in the abominable rites of Baalpeor. All these events were known to the inhabitants of Jericho, and there were many who shared Rahab’s conviction, though they refused to obey it, that Jehovah, the God of Israel, “is God in heaven above, and upon the earth beneath.” Deuteronomy 4:39. Like the men before the Flood, the Canaanites lived only to blaspheme Heaven and defile the earth. And both love and justice demanded the prompt execution of these rebels against God and foes to man.

How easily the armies of heaven brought down the walls of Jericho, that proud city whose bulwarks, forty years before, had struck terror to the unbelieving spies! The Mighty One of Israel had said, “I have given into thine hand Jericho.” Joshua 6:2. Against that word human strength was powerless. (PP 492.3) MC VC

“By faith the walls of Jericho fell down.” Hebrews 11:30. The Captain of the Lord’s host communicated only with Joshua; He did not reveal Himself to all the congregation, and it rested with them to believe or doubt the words of Joshua, to obey the commands given by him in the name of the Lord, or to deny his authority. They could not see the host of angels who attended them under the leadership of the Son of God. They might have reasoned: “What unmeaning movements are these, and how ridiculous the performance of marching daily around the walls of the city, blowing trumpets of rams’ horns. This can have no effect upon those towering fortifications.” But the very plan of continuing this ceremony through so long a time prior to the final overthrow of the walls afforded opportunity for the development of faith among the Israelites. It was to be impressed upon their minds that their strength was not in the wisdom of man, nor in his might, but only in the God of their salvation. They were thus to become accustomed to relying wholly upon their divine Leader. (PP 493.1) MC VC

God will do great things for those who trust in Him. The reason why His professed people have no greater strength is that they trust so much to their own wisdom, and do not give the Lord an opportunity to reveal His power in their behalf. He will help His believing children in every emergency if they will place their entire confidence in Him and faithfully obey Him. (PP 493.2) MC VC

Soon after the fall of Jericho, Joshua determined to attack Ai, a small town among the ravines a few miles to the west of the Jordan Valley. Spies sent to this place brought back the report that the inhabitants were but few, and that only a small force would be needed to overthrow it. (PP 493.3) MC VC

The great victory that God had gained for them had made the Israelites self-confident. Because He had promised them the land of Canaan they felt secure, and failed to realize that divine help alone could give them success. Even Joshua laid his plans for the conquest of Ai without seeking counsel from God. (PP 493.4) MC VC

The Israelites had begun to exalt their own strength and to look with contempt upon their foes. An easy victory was expected, and three thousand men were thought sufficient to take the place. These rushed to the attack without the assurance that God would be with them. They advanced nearly to the gate of the city, only to encounter the most determined resistance. Panic-stricken at the numbers and thorough preparation of their enemies, they fled in confusion down the steep descent. The Canaanites were in hot pursuit; “they chased them from before the gate, ... and smote them in the going down.” Joshua 7:5. Though the loss was small as to numbers—but thirty-six men being slain—the defeat was disheartening to the whole congregation. “The hearts of the people melted, and became as water.” Joshua 7:5. This was the first time they had met the Canaanites in actual battle, and if put to flight before the defenders of this little town, what would be the result in the greater conflicts before them? Joshua looked upon their ill success as an expression of God’s displeasure, and in distress and apprehension he “rent his clothes, and fell to the earth upon his face before the ark of the Lord until the eventide, he and the elders of Israel, and put dust upon their heads.” Joshua 7:6.
