19 Remember the great terrors the Lord your God sent against them. You saw it all with your own eyes! And remember the miraculous signs and wonders, and the strong hand and powerful arm with which he brought you out of Egypt. The Lord your God will use this same power against all the people you fear. 20 And then the Lord your God will send terror to drive out the few survivors still hiding from you! 21 "No, do not be afraid of those nations, for the Lord your God is among you, and he is a great and awesome God. 22 The Lord your God will drive those nations out ahead of you little by little. You will not clear them away all at once, otherwise the wild animals would multiply too quickly for you. 23 But the Lord your God will hand them over to you. He will throw them into complete confusion until they are destroyed. 24 He will put their kings in your power, and you will erase their names from the face of the earth. No one will be able to stand against you, and you will destroy them all. 25 "You must burn their idols in fire, and you must not covet the silver or gold that covers them. You must not take it or it will become a trap to you, for it is detestable to the Lord your God. 26 Do not bring any detestable objects into your home, for then you will be destroyed, just like them. You must utterly detest such things, for they are set apart for destruction.

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.
