71 "When the Lord your God brings you into the land you are about to enter and occupy, he will clear away many nations ahead of you: the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites. These seven nations are greater and more numerous than you. 2 When the Lord your God hands these nations over to you and you conquer them, you must completely destroy them. Make no treaties with them and show them no mercy. 3 You must not intermarry with them. Do not let your daughters and sons marry their sons and daughters, 4 for they will lead your children away from me to worship other gods. Then the anger of the Lord will burn against you, and he will quickly destroy 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.
