19 the great trials which your eyes saw, the signs and the wonders, the mighty hand and the outstretched arm, by which the Lord your God brought you out. So shall the Lord your God do to all the peoples of whom you are afraid. 20 Moreover the Lord your God will send the hornet among them until those who are left, who hide themselves from you, are destroyed. 21 You shall not be terrified of them; for the Lord your God, the great and awesome God, is among you. 22 And the Lord your God will drive out those nations before you little by little; you will be unable to destroy them at once, lest the beasts of the field become too numerous for you. 23 But the Lord your God will deliver them over to you, and will inflict defeat upon them until they are destroyed. 24 And He will deliver their kings into your hand, and you will destroy their name from under heaven; no one shall be able to stand against you until you have destroyed them. 25 You shall burn the carved images of their gods with fire; you shall not covet the silver or gold that is on them, nor take it for yourselves, lest you be snared by it; for it is an abomination to the Lord your God. 26 Nor shall you bring an abomination into your house, lest you be doomed to destruction like it. You shall utterly detest it and utterly abhor it, for it is an accursed thing.

Matthew Henry's Commentary on Deuteronomy 7:19-33

Commentary on Deuteronomy 7:12-26

(Read Deuteronomy 7:12-26)

We are in danger of having fellowship with the works of darkness if we take pleasure in fellowship with those who do such works. Whatever brings us into a snare, brings us under a curse. Let us be constant to our duty, and we cannot question the constancy of God's mercy. Diseases are God's servants; they go where he sends them, and do what he bids them. It is therefore good for the health of our bodies, thoroughly to mortify the sin of our souls; which is our rule of duty. Yet sin is never totally destroyed in this world; and it actually prevails in us much more than it would do, if we were watchful and diligent. In all this the Lord acts according to the counsel of his own will; but that counsel being hid from us, forms no excuse for our sloth and negligence, of which it is in no degree the cause. We must not think, that because the deliverance of the church, and the destruction of the enemies of the soul, are not done immediately, therefore they will never be done. God will do his own work in his own method and time; and we may be sure that they are always the best. Thus corruption is driven out of the hearts of believers by little and little. The work of sanctification is carried on gradually; but at length there will be a complete victory. Pride, security, and other sins that are common effects of prosperity, are enemies more dangerous than beasts of the field, and more apt to increase upon us.
