41 "And now, O Israel, give heed to the statutes and the ordinances which I teach you, and do them; that you may live, and go in and take possession of the land which the Lord, the God of your fathers, gives you. 2 You shall not add to the word which I command you, nor take from it; that you may keep the commandments of the Lord your God which I command you. 3 Your eyes have seen what the Lord did at Ba'al-pe'or; for the Lord your God destroyed from among you all the men who followed the Ba'al of Pe'or; 4 but you who held fast to the Lord your God are all alive this day. 5 Behold, I have taught you statutes and ordinances, as the Lord my God commanded me, that you should do them in the land which you are entering to take possession of it. 6 Keep them and do them; for that will be your wisdom and your understanding in the sight of the peoples, who, when they hear all these statutes, will say, 'Surely this great nation is a wise and understanding people.' 7 For what great nation is there that has a god so near to it as the Lord our God is to us, whenever we call upon him? 8 And what great nation is there, that has statutes and ordinances so righteous as all this law which I set before you this day?
9 "Only take heed, and keep your soul diligently, lest you forget the things which your eyes have seen, and lest they depart from your heart all the days of your life; make them known to your children and your children's children--

Commentary on Deuteronomy 4:1-23
(Read Deuteronomy 4:1-23)
The power and love of God to Israel are here made the ground and reason of a number of cautions and serious warnings; and although there is much reference to their national covenant, yet all may be applied to those who live under the gospel. What are laws made for but to be observed and obeyed? Our obedience as individuals cannot merit salvation; but it is the only evidence that we are partakers of the gift of God, which is eternal life through Jesus Christ, Considering how many temptations we are compassed with, and what corrupt desires we have in our bosoms, we have great need to keep our hearts with all diligence. Those cannot walk aright, who walk carelessly. Moses charges particularly to take heed of the sin of idolatry. He shows how weak the temptation would be to those who thought aright; for these pretended gods, the sun, moon, and stars, were only blessings which the Lord their God had imparted to all nations. It is absurd to worship them; shall we serve those that were made to serve us? Take heed lest ye forget the covenant of the Lord your God. We must take heed lest at any time we forget our religion. Care, caution, and watchfulness, are helps against a bad memory.
