10 When you draw near to a town to fight against it, offer it terms of peace. 11 If it accepts your terms of peace and surrenders to you, then all the people in it shall serve you at forced labor. 12 If it does not submit to you peacefully, but makes war against you, then you shall besiege it; 13 and when the Lord your God gives it into your hand, you shall put all its males to the sword. 14 You may, however, take as your booty the women, the children, livestock, and everything else in the town, all its spoil. You may enjoy the spoil of your enemies, which the Lord your God has given you. 15 Thus you shall treat all the towns that are very far from you, which are not towns of the nations here. 16 But as for the towns of these peoples that the Lord your God is giving you as an inheritance, you must not let anything that breathes remain alive. 17 You shall annihilate them-the Hittites and the Amorites, the Canaanites and the Perizzites, the Hivites and the Jebusites-just as the Lord your God has commanded, 18 so that they may not teach you to do all the abhorrent things that they do for their gods, and you thus sin against the Lord your God.

Commentary on Deuteronomy 20:10-12
(Read Deuteronomy 20:10-12)
The Israelites are here directed about the nations on whom they made war. Let this show God's grace in dealing with sinners. He proclaims peace, and beseeches them to be reconciled. Let it also show us our duty in dealing with our brethren. Whoever are for war, we must be for peace. Of the cities given to Israel, none of their inhabitants must be left. Since it could not be expected that they should be cured of their idolatry, they would hurt Israel. These regulations are not the rules of our conduct, but Christ's law of love. The horrors of war must fill the feeling heart with anguish upon every recollection; and are proofs of the wickedness of man, the power of Satan, and the just vengeance of God, who thus scourges a guilty world. But how dreadful their case who are engaged in unequal conflict with their Maker, who will not submit to render him the easy tribute of worship and praise! Certain ruin awaits them. Let neither the number nor the power of the enemies of our souls dismay us; nor let even our own weakness cause us to tremble or to faint. The Lord will save us; but in this war let none engage whose hearts are fond of the world, or afraid of the cross and the conflict. Care is here taken that in besieging cities the fruit-trees should not be destroyed. God is a better friend to man than he is to himself; and God's law consults our interests and comforts; while our own appetites and passions, which we indulge, are enemies to our welfare. Many of the Divine precepts restrain us from destroying that which is for our life and food. The Jews understand this as forbidding all wilful waste upon any account whatsoever. Every creature of God is good; as nothing is to be refused, so nothing is to be abused. We may live to want what we carelessly waste.
