Thou shalt therefore keep the commandments, and the statutes, and the judgments,.... The laws, moral, ceremonial, and judicial, urged thereunto both by promises and threatenings, in hopes of reward, and through fear of punishment:

which I command thee this day, to do them; in the name of the Lord, and by his authority; by virtue of which he made a new declaration of them to put them in mind of them in order to observe them.

This energy of the grace and holiness of the faithful covenant God was a powerful admonition to keep the divine commandments.

Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day, to do them.

11-26. Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day-In the covenant into which God entered with Israel, He promised to bestow upon them a variety of blessings so long as they continued obedient to Him as their heavenly King. He pledged His veracity that His infinite perfections would be exerted for this purpose, as well as for delivering them from every evil to which, as a people, they would be exposed. That people accordingly were truly happy as a nation, and found every promise which the faithful God made to them amply fulfilled, so long as they adhered to that obedience which was required of them. See a beautiful illustration of this in Ps 144:12-15.

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.
