6 For you are a holy people, who belong to the Lord your God. Of all the people on earth, the Lord your God has chosen you to be his own special treasure. 7 "The Lord did not set his heart on you and choose you because you were more numerous than other nations, for you were the smallest of all nations! 8 Rather, it was simply that the Lord loves you, and he was keeping the oath he had sworn to your ancestors. That is why the Lord rescued you with such a strong hand from your slavery and from the oppressive hand of Pharaoh, king of Egypt.
Matthew Henry's Commentary on Deuteronomy 7:6-8
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.
