And there shall cleave naught of the cursed thing - As God did not permit them to take the spoils of these idolatrous cities, they could be under no temptation to make war upon them. It could only be done through a merely religious motive, in obedience to the command of God, as they could have no profit by the subversion of such places. How few religious wars would there ever have been in the world had they been regulated by this principle: "Thou shalt neither extend thy territory, nor take any spoils!"

And there shall cleave nought of the cursed thing to thine hand,.... That is, they might not take anything whatever to their own use; for all being devoted to destruction, was cursed, and brought a curse upon the man that should make it his own property, as Achan did, when Jericho was destroyed:

that the Lord may turn from the fierceness of his anger; stirred up by the idolatry of the city:

and show thee mercy, and have compassion upon thee; who, seeing wrath gone forth, might dread the consequences, lest it should spread itself further:

and multiply thee, as he hath sworn to thy fathers; Abraham, Isaac, and Jacob; this is observed to encourage them to execute his orders punctually in the destruction of the idolatrous city; since God could and would multiply them, as he had promised their fathers, with an oath, so that they should not be the fewer by such an instance of his severity.

To enforce this command still more strongly, it is expressly stated, that of all that was burned, nothing whatever was to cleave or remain hanging to the hand of Israel, that the Lord might turn from His wrath and have compassion upon the nation, i.e., not punish the sin of one town upon the nation as a whole, but have mercy upon it and multiply it, - make up the diminution consequent upon the destruction of the inhabitants of that town, and so fulfil the promise given to the fathers of the multiplication of their seed.

And there shall cleave nought of the {k} cursed thing to thine hand: that the LORD may turn from the fierceness of his anger, and shew thee mercy, and have compassion upon thee, and multiply thee, as he hath sworn unto thy fathers;

(k) Of the spoil of that idolatrous and cursed city, read De 7:26, Jos 7:11.

13:17 Multiply thee - So thou shalt have no loss of thy numbers by cutting off so many people.

cursed: or, devoted

17. there shall cleave naught of the cursed thing to thine hand-No spoil shall be taken from a city thus solemnly devoted to destruction. Every living creature must be put to the sword-everything belonging to it reduced to ashes-that nothing but its infamy may remain.

13:12-18 Here is the case of a city revolting from the God of Israel, and serving other gods. The crime is supposed to be committed by one of the cities of Israel. Even when they were ordered to preserve their religion by force, yet they were not allowed to bring others to it by fire and sword. Spiritual judgments under the Christian dispensation are more terrible than the execution of criminals; we have not less cause than the Israelites had, to fear the Divine wrath. Let us then fear the spiritual idolatry of covetousness, and the love of worldly pleasure; and be careful not to countenance them in our families, by our example or by the education of our children. May the Lord write his law and truth in our hearts, there set up his throne, and shed abroad his love!
