Deuteronomy 13:17

17 Nothing set apart for destruction is to remain in your hand, so that the Lord will turn from His burning anger and grant you mercy, show you compassion, and multiply you as He swore to your fathers.

Deuteronomy 13:17 Meaning and Commentary

Deuteronomy 13:17

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.

Deuteronomy 13:17 In-Context

15 you must strike down the inhabitants of that city with the sword. Completely destroy everyone in it as well as its livestock with the sword.
16 You are to gather all its spoil in the middle of the city square and completely burn up the city and all its spoil for the Lord your God. The city must remain a mound of ruins forever; it is not to be rebuilt.
17 Nothing set apart for destruction is to remain in your hand, so that the Lord will turn from His burning anger and grant you mercy, show you compassion, and multiply you as He swore to your fathers.
18 This [will occur] if you obey the Lord your God, keeping all His commands I am giving you today, doing what is right in the sight of the Lord your God.
