Problem: This passage states that the Israelites “utterly destroyed all that was in the city, both man and woman, young and old, ox and sheep and donkey, with the edge of the sword.” But how can such a ruthless destruction of innocent life and property be justified?
Solution: First, the Canaanites were far from “innocent.” The description of their sins in Leviticus 18 is vivid: “The land is defiled; therefore I visit the punishment of its iniquity upon it, and the land vomits out its inhabitants” (v. 25). They were cancerously immoral, “defiled” with every kind of “abomination,” including child sacrifice (vv. 21, 24, 26).
Second, it must be remembered that God had given the people of Palestine over 400 years to repent of their wickedness. The people of that land had every opportunity to turn from their wickedness. According to Genesis 15:16, God told Abraham that in 400 years the descendants of Abraham would return to inherit this land, but that the iniquity of the people was not yet full. This prophetic statement indicated that God would not destroy the people of the land, including those who dwelt in Jericho, until their sins were such that their guilt merited their complete destruction in judgment.
Third, as for the killing of the little children, several things should be noted. (1) Given the cancerous state of the society into which they were born, they had no chance to avoid its fatal pollution. (2) Children who die before the age of accountability go to heaven (see comments on 2 Sam. 12:23). This was an act of God’s mercy to their souls to take them into His holy presence from such an unholy environment. (3) God is sovereign over life (Deut. 32:39; Job 1:21) and can order its end according to His will and in view of the creature’s ultimate good.
Fourth, Joshua and the people of Israel were acting according to the direct command of God, not on their own initiative. The destruction of Jericho was carried out by the army of Israel, but the army of Israel was the instrument of judgment upon the sins of these people by the righteous Judge of all the earth. Consequently, anyone who would question the justification of this act is questioning God’s justice.
Fifth, it was necessary to completely exterminate any trace of the city and its people. If anything had remained, except that which was taken into the treasure house of the Lord, there would have always been the threat of heathen influence to pull the people away from the pure worship of the Lord. Sometimes radical surgery is required to completely eliminate a deadly cancer from the body.
