Joshua 6:26 And Joshua adjured them at that time, saying, Cursed be the man before the Lord, that riseth up and buildeth this city Jericho: he shall lay the foundation thereof in his firstborn, and in his youngest son shall he set up the gates of it. 27 So the Lord was with Joshua; and his fame was noised throughout all the country.
[Patriarchs & Prophets pp 492] 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.
Ecclesiastes 8:11 Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil. 12 Though a sinner do evil an hundred times, and his days be prolonged, yet surely I know that it shall be well with them that fear God, which fear before him: 13 But it shall not be well with the wicked, neither shall he prolong his days, which are as a shadow; because he feareth not before God.
May The lord add His blessing to the study of His word. God bless!
