Therefore thou shalt keep the commandments of the Lord thy God,.... Not only because they are the commands of God, and of a covenant God and Father, which are reasons sufficient for the observance of them; but because the Lord had dealt so bountifully with them, in providing food and raiment for them in the wilderness, which always continued with them; and because, when he afflicted them, it was a fatherly chastisement, with great tenderness and compassion, and for their good; all which laid them under obligations to keep the commands of God, whatsoever he had enjoined them, whether of the moral, ceremonial, or judicial kind:

to walk in his ways, and to fear him; to walk in the ways he directed, to be under an awe of his majesty, a fear of offending him, and a reverential affection for him, such as children have to a father.

The design of this education was to train them to keep His commandments, that they might walk in His ways and fear Him (Deuteronomy 6:24).

Therefore thou shalt keep the commandments of the LORD thy God, to walk in his ways, and to fear him.

8:1-9 Obedience must be, 1. Careful, observe to do; 2. Universal, to do all the commandments; and 3. From a good principle, with a regard to God as the Lord, and their God, and with a holy fear of him. To engage them to this obedience. Moses directs them to look back. It is good to remember all the ways, both of God's providence and grace, by which he has led us through this wilderness, that we may cheerfully serve him and trust in him. They must remember the straits they were sometimes brought into, for mortifying their pride, and manifesting their perverseness; to prove them, that they and others might know all that was in their heart, and that all might see that God chose them, not for any thing in them which might recommend them to his favour. They must remember the miraculous supplies of food and raiment granted them. Let none of God's children distrust their Father, nor take any sinful course for the supply of their necessities. Some way or other, God will provide for them in the way of duty and honest diligence, and verily they shall be fed. It may be applied spiritually; the word of God is the food of the soul. Christ is the word of God; by him we live. They must also remember the rebukes they had been under, and not without need. This use we should make of all our afflictions; by them let us be quickened to our duty. Moses also directs them to look forward to Canaan. Look which way we will, both to look back and to look forward, to Canaan. Look which way we will, both to look back and to look forward will furnish us with arguments for obedience. Moses saw in that land a type of the better country. The gospel church is the New Testament Canaan, watered with the Spirit in his gifts and graces, planted with trees of righteousness, bearing fruits of righteousness. Heaven is the good land, in which nothing is wanting, and where is fulness of joy.
