Thou shalt smite them, etc. - These idolatrous nations were to be utterly destroyed, and all the others also which were contiguous to the boundaries of the promised land, provided they did not renounce their idolatry and receive the true faith: for if they did not, then no covenant was to be made with them on any secular or political consideration whatever; no mercy was to be shown to them, because the cup of their iniquity also was now full; and they must either embrace, heartily embrace, the true religion, or be cut off.

And when the Lord thy God shall deliver them before thee,.... Into their hands:

thou shalt smite them, and utterly destroy them; men, women, and children; which was ordered not merely to make way and room for the people of Israel to inherit their land, but as a punishment for capital crimes they had been guilty of, such as idolatry, incest, murder, &c. wherefore though they were reprieved for a while for Israel's sake, till their time was come to possess the land, they were at length righteously punished; which observed, abates the seeming severity exercised upon them:

thou shalt make no covenant with them; to dwell in their cities and houses, and enjoy their lands and estates, on any condition whatever; and though they did make a league with the Gibeonites, that was obtained by fraud, they pretending not to be of the land of Canaan, but to come from a very distant country:

nor show mercy unto them; by sparing their lives, bestowing any favours upon them, or giving them any help and assistance when in distress: the Jews extend this to all other Heathen nations besides these seven; wherefore, if an Israelite, as Maimonides (z) says, should see a Gentile perishing, or plunged into a river, he may not take him out, nor administer medicine to a sick person. Hence Juvenal (a) the poet upbraids them with their unkindness and incivility; and says that Moses delivered it as a Jewish law, in a secret volume of his, perhaps referring to this book of Deuteronomy, that the Jews might not direct a poor traveller in his way unless he was one of their religion, nor one athirst to a fountain of water; and which led Tacitus (b), the Heathen historian, to make this remark upon them, that they entertained an hostile hatred against all other people.

And when the LORD thy God shall deliver them {a} before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:

(a) Into thy power.

2-6. thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them-This relentless doom of extermination which God denounced against those tribes of Canaan cannot be reconciled with the attributes of the divine character, except on the assumption that their gross idolatry and enormous wickedness left no reasonable hope of their repentance and amendment. If they were to be swept away like the antediluvians or the people of Sodom and Gomorrah, as incorrigible sinners who had filled up the measure of their iniquities, it mattered not to them in what way the judgment was inflicted; and God, as the Sovereign Disposer, had a right to employ any instruments that pleased Him for executing His judgments. Some think that they were to be exterminated as unprincipled usurpers of a country which God had assigned to the posterity of Eber and which had been occupied ages before by wandering shepherds of that race, till, on the migration of Jacob's family into Egypt through the pressure of famine, the Canaanites overspread the whole land, though they had no legitimate claim to it, and endeavored to retain possession of it by force. In this view their expulsion was just and proper. The strict prohibition against contracting any alliances with such infamous idolaters was a prudential rule, founded on the experience that "evil communications corrupt good manners" [1Co 15:33], and its importance or necessity was attested by the unhappy examples of Solomon and others in the subsequent history of Israel.

7:1-11 Here is a strict caution against all friendship and fellowship with idols and idolaters. Those who are in communion with God, must have no communication with the unfruitful works of darkness. Limiting the orders to destroy, to the nations here mentioned, plainly shows that after ages were not to draw this into a precedent. A proper understanding of the evil of sin, and of the mystery of a crucified Saviour, will enable us to perceive the justice of God in all his punishments, temporal and eternal. We must deal decidedly with our lusts that war against our souls; let us not show them any mercy, but mortify, and crucify, and utterly destroy them. Thousands in the world that now is, have been undone by ungodly marriages; for there is more likelihood that the good will be perverted, than that the bad will be converted. Those who, in choosing yoke-fellows, keep not within the bounds of a profession of religion, cannot promise themselves helps meet for them.
