41 So now, Israel, give heed to the statutes and ordinances that I am teaching you to observe, so that you may live to enter and occupy the land that the Lord, the God of your ancestors, is giving you. 2 You must neither add anything to what I command you nor take away anything from it, but keep the commandments of the Lord your God with which I am charging you. 3 You have seen for yourselves what the Lord did with regard to the Baal of Peor-how the Lord your God destroyed from among you everyone who followed the Baal of Peor, 4 while those of you who held fast to the Lord your God are all alive today. 5 See, just as the Lord my God has charged me, I now teach you statutes and ordinances for you to observe in the land that you are about to enter and occupy. 6 You must observe them diligently, for this will show your wisdom and discernment to the peoples, who, when they hear all these statutes, will say, "Surely this great nation is a wise and discerning people!" 7 For what other great nation has a god so near to it as the Lord our God is whenever we call to him? 8 And what other great nation has statutes and ordinances as just as this entire law that I am setting before you today?
9 But take care and watch yourselves closely, so as neither to forget the things that your eyes have seen nor to let them slip from your mind all the days of your life; make them known to your children and your children's children- 10 how you once stood before the Lord your God at Horeb, when the Lord said to me, "Assemble the people for me, and I will let them hear my words, so that they may learn to fear me as long as they live on the earth, and may teach their children so"; 11 you approached and stood at the foot of the mountain while the mountain was blazing up to the very heavens, shrouded in dark clouds. 12 Then the Lord spoke to you out of the fire. You heard the sound of words but saw no form; there was only a voice. 13 He declared to you his covenant, which he charged you to observe, that is, the ten commandments; and he wrote them on two stone tablets.

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.
