19 the great trials that your eyes saw, the signs and wonders, the mighty hand and the outstretched arm by which the Lord your God brought you out. The Lord your God will do the same to all the peoples of whom you are afraid. 20 Moreover, the Lord your God will send the pestilence against them, until even the survivors and the fugitives are destroyed. 21 Have no dread of them, for the Lord your God, who is present with you, is a great and awesome God. 22 The Lord your God will clear away these nations before you little by little; you will not be able to make a quick end of them, otherwise the wild animals would become too numerous for you. 23 But the Lord your God will give them over to you, and throw them into great panic, until they are destroyed. 24 He will hand their kings over to you and you shall blot out their name from under heaven; no one will be able to stand against you, until you have destroyed them. 25 The images of their gods you shall burn with fire. Do not covet the silver or the gold that is on them and take it for yourself, because you could be ensnared by it; for it is abhorrent to the Lord your God. 26 Do not bring an abhorrent thing into your house, or you will be set apart for destruction like it. You must utterly detest and abhor it, for it is set apart for destruction.

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.
