19 the great trials which thine eyes saw, and the signs, and the wonders, and the mighty hand, and the outstretched arm, whereby Jehovah thy God brought thee out: so shall Jehovah thy God do unto all the peoples of whom thou art afraid. 20 Moreover Jehovah thy God will send the hornet among them, until they that are left, and hide themselves, perish from before thee. 21 Thou shalt not be affrighted at them; for Jehovah thy God is in the midst of thee, a great God and a terrible. 22 And Jehovah thy God will cast out those nations before thee by little and little: thou mayest not consume them at once, lest the beasts of the field increase upon thee. 23 But Jehovah thy God will deliver them up before thee, and will discomfit them with a great discomfiture, until they be destroyed. 24 And he will deliver their kings into thy hand, and thou shalt make their name to perish from under heaven: there shall no man be able to stand before thee, until thou have destroyed them. 25 The graven images of their gods shall ye burn with fire: thou shalt not covet the silver or the gold that is on them, nor take it unto thee, lest thou be snared therein; for it is an abomination to Jehovah thy God. 26 And thou shalt not bring an abomination into thy house, and become a devoted thing like unto it: thou shalt utterly detest it, and thou shalt utterly abhor it; for it is a devoted thing.

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.
