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. PP 492.1…
"And when the Lord thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:"
Ellen White directly references Deuteronomy 7:2 in this passage.
"But of the cities of these people, which the Lord thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth:"
Ellen White directly references Deuteronomy 20:16 in this passage.
"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.” 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. PP 492.2"
"And she said unto the men, I know that the Lord hath given you the land, and that your terror is fallen upon us, and that all the inhabitants of the land faint because of you. For we have heard how the Lord dried up the water of the Red sea for you, when ye came out of Egypt; and what ye did unto the two kings of the Amorites, that were on the other side Jordan, Sihon and Og, whom ye utterly destroyed. And as soon as we had heard these things, our hearts did melt, neither did there remain any more courage in any man, because of you: for the Lord your God, he is God in heaven above, and in earth beneath."
EGW directly references and expands upon Rahab's statement in Joshua 2:11, making the connection explicit.
"The people shall hear, and be afraid: sorrow shall take hold on the inhabitants of Palestina."
Both passages discuss the fear and awareness of God's power among the inhabitants of the land. While Exodus 15:14 is a general statement about fear, the EGW passage provides specific examples of events that would have caused that fear, connecting it to the context of the Canaanites and Jericho.
"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.” Against that word human strength was powerless. PP 492.3"
"And the Lord said unto Joshua, See, I have given into thine hand Jericho, and the king thereof, and the mighty men of valour."
The EGW passage directly quotes Joshua 6:2: "I have given into thine hand Jericho."
"There is no king saved by the multitude of an host: a mighty man is not delivered by much strength."
Both passages highlight the limitations of human strength against divine power. While EGW focuses on the fall of Jericho, and Psalms 33:16 speaks more generally, the underlying principle is the same.
"He giveth power to the faint; and to them that have no might he increaseth strength."
Both passages touch on the theme of divine power overcoming human weakness. EGW illustrates this through the fall of Jericho, while Isaiah 40:29 speaks more broadly about God giving strength. The connection is thematic but not a direct allusion.
