41 "Now, O Israel, listen to the statutes and the judgments which I teach you to observe, that you may live, and go in and possess the land which the Lord God of your fathers is giving 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 Baal Peor; for the Lord your God has destroyed from among you all the men who followed Baal of Peor. 4 But you who held fast to the Lord your God are alive today, every one of you. 5 Surely I have taught you statutes and judgments, just as the Lord my God commanded me, that you should act according to them in the land which you go to possess. 6 Therefore be careful to observe them; for this is your wisdom and your understanding in the sight of the peoples who will hear all these statutes, and say, 'Surely this great nation is a wise and understanding people.' 7 For what great nation is there that has God so near to it, as the Lord our God is to us, for whatever reason we may call upon Him? 8 And what great nation is there that has such statutes and righteous judgments as are in all this law which I set before you this day?
9 "Only take heed to yourself, and diligently keep yourself, lest you forget the things your eyes have seen, and lest they depart from your heart all the days of your life. And teach them to your children and your grandchildren, 10 especially concerning the day you stood before the Lord your God in Horeb, when the Lord said to me, 'Gather the people to Me, and I will let them hear My words, that they may learn to fear Me all the days they live on the earth, and that they may teach their children.' 11 Then you came near and stood at the foot of the mountain, and the mountain burned with fire to the midst of heaven, with darkness, cloud, and thick darkness. 12 And the Lord spoke to you out of the midst of the fire. You heard the sound of the words, but saw no form; you only heard a voice. 13 So He declared to you His covenant which He commanded you to perform, the Ten Commandments; and He wrote them on two tablets of stone.

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.
