71 When Jehovah thy God shall bring thee into the land whither thou goest to possess it, and shall cast out many nations from before thee, the Hittites, and the Girgashites, and the Amorites, and the Canaanites, and the Perizzites, and the Hivites, and the Jebusites, seven nations greater and mightier than thou, 2 and when Jehovah thy God shall give them up before thee and thou shalt smite them, then shalt thou utterly destroy them: thou shalt make no covenant with them, nor shew mercy unto them. 3 And thou shalt make no marriages with them: thy daughter thou shalt not give unto his son, nor take his daughter for thy son; 4 for he will turn away thy son from following me, and they will serve other gods, and the anger of Jehovah will be kindled against you, and he will destroy thee quickly.
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.
