Israel Warned of the Idolatry of Canaan

71 "When the Lord your God brings you into the land that you are entering to take possession of it, and clears away many nations before you, the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations more numerous and mightier than yourselves, 2 and when the Lord your God gives them over to you, and you defeat them, then you must devote them to complete destruction.[1] You shall make no covenant with them and show no mercy to them. 3 You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons,

Matthew Henry's Commentary on Deuteronomy 7:1-3

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.
