71 When God, your God, brings you into the country that you are about to enter and take over, he will clear out the superpowers that were there before you: the Hittite, the Girgashite, the Amorite, the Canaanite, the Perizzite, the Hivite, and the Jebusite. Those seven nations are all bigger and stronger than you are. 2 God, your God, will turn them over to you and you will conquer them. You must completely destroy them, offering them up as a holy destruction to God. Don't make a treaty with them. Don't let them off in any way. 3 Don't marry them: Don't give your daughters to their sons and don't take their daughters for your sons - 4 before you know it they'd involve you in worshiping their gods, and God would explode in anger, putting a quick end to you.
Matthew Henry's Commentary on Deuteronomy 7:1-4
Commentary on Deuteronomy 7:1-11
(Read Deuteronomy 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.
