That thou mayest {a} fear the LORD thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son's son, all the days of thy life; and that thy days may be prolonged.

(a) A reverent face and love for God is the first beginning to keeping God's commandments.

Matthew Henry's Concise Commentary

6:1-3 In this and the like passages, the commandments seem to denote the moral law, the statues the ceremonial law, and the judgments the law by which the judges decided. Moses taught the people all that, and that only, which God commanded him to teach. Thus Christ's ministers are to teach his churches all he has commanded, neither more nor less, Mt 28:20. The fear of God in the heart will be the most powerful principle of obedience. It is highly desirable that not we only, but our children, and our children's children, may fear the Lord. Religion and righteousness advance and secure the prosperity of any people.

Matthew Henry's Whole Bible Commentary

Chapter 6

Moses, in this chapter, goes on with his charge to Israel, to be sure to keep up their religion in Canaan. It is much the same with ch. 4. I. His preface is a persuasive to obedience (v. 1-3). II. He lays down the great principles of obedience. The first truth to be believed, That God is one (v. 4). The first duty to be done, To love him with all our heart (v. 5). III. He prescribes the means for keeping up religion (v. 6-9). IV. He cautions them against those things which would be the ruin of religion-abuse of plenty (v. 10-12), inclination to idolatry (v. 14, 15), and gives them some general precepts (v. 13, 16-18). V. He directs them what instructions to give their children (v. 20, etc.).

Verses 1-3

Observe here, 1. That Moses taught the people all that, and that only, which God commanded him to teach them, v. 1. Thus Christ's ministers are to teach his churches all that he has commanded, and neither more nor less, Mt. 28:20. 2. That the end of their being taught was that they might do as they were taught (v. 1), might keep God's statutes (v. 2), and observe to do them, v. 3. Good instructions from parents and ministers will but aggravate our condemnation if we do not live up to them. 3. That Moses carefully endeavoured to fix them for God and godliness, now that they were entering upon the land of Canaan, that they might be prepared for the comforts of that land, and fortified against the snares of it, and now that they were setting out in the world might set out well. 4. That the fear of God in the heart will be the most powerful principle of obedience: That thou mightest fear the Lord thy God, to keep all his statutes, v. 2. 5. The entail of religion in a family, or country, is the best entail: it is highly desirable that not we only, but our children, and our children's children, may fear the Lord. 6. Religion and righteousness advance and secure the prosperity of any people. Fear God, and it shall be well with thee. Those that are well taught, if they do what they are taught, shall be well fed too, as Israel in the land flowing with milk and honey, v. 3.
