Here, I. Moses repeats the directions he had given for the guidance and assistance of the people in their obedience, and for the keeping up of religion among them (Deut. 11:18-20), which is much to the same purport with what we had before, Deut. 6:6 Let us all be directed by the three rules here given:?1. Let our hearts be filled with the word of God: Lay up these words in your heart and in your soul. The heart must be the treasury or store-house in which the word of God must be laid up, to be used upon all occasions. We cannot expect good practices in the conversation, unless there be good thoughts, good affections, and good principles, in the heart. 2. Let our eyes be fixed upon the word of God. ?Bind these words for a sign upon your hand, which is always in view (Isa. 49:16), and as frontlets between your eyes, which you cannot avoid the sight of; let them be as ready and familiar to you, and have your eye as constantly upon them, as if they were written upon your door-posts, and could not be overlooked either when you go out or when you come in.? Thus we must lay God?s judgments before us, having a constant regard to them, as the guide of our way, as the rule of our work, Ps. 119:30. 3. Let our tongues be employed about the word of God. Let it be the subject of our familiar discourse, wherever we are; especially with our children, who must be taught the service of God, as the one thing needful, much more needful than either the rules of decency or the calling they must live by in this world. Great care and pains must be taken to acquaint children betimes, and to affect them, with the word of God and the wondrous things of his law. Nor will any thing contribute more to the prosperity and perpetuity of religion in a nation than the good education of children: if the seed be holy, it is the substance of a land.
II. He repeats the assurances he had before given them, in God?s name, of prosperity and success if they were obedient. 1. They should have a happy settlement, Deut. 11:21. Their days should be multiplied; and, when they were fulfilled, the days of their children likewise should be many, as the days of heaven, that is, Canaan should be sure to them and their heirs for ever, as long as the world stands, if they did not by their own sin throw themselves out of it. 2. It should not be in the power of their enemies to give them any disturbance, nor make them upon any account uneasy. ?If you will keep God?s commandments, and be careful to do your duty (Deut. 11:22), God will not only crown the labours of the husbandman with plenty of the fruits of the earth, but he will own and succeed the more glorious undertakings of the men of war. Victory shall attend your arms; which way soever they turn, God will drive out these nations, and put you in possession of their land,? Deut. 11:23, 24. Their territories should be enlarged to the utmost extent of the promise, Gen. 15:18. And all their neighbours should stand in awe of them, Deut. 11:25. Nothing contributes more to the making of a nation considerable abroad, valuable to its friends and formidable to its enemies, than religion reigning in it; for who can be against those that have God for them? And he is certainly for those that are sincerely for him, Prov. 14:34.
