Now that Moses had largely repeated the commands which the people were to observe as their part of the covenant, and the promises and threatenings which God would make good (according as they behaved themselves) as part of the covenant, the whole is here summed up in a federal transaction. The covenant formerly made is here renewed, and Moses, who was before, is still, the mediator of it (Deu 29:1): The Lord commanded Moses to make it. Moses himself, though king in Jeshurun, could not make the covenant any otherwise than as God gave him instructions. It does not lie in the power of ministers to fix the terms of the covenant; they are only to dispense the seals of it. This is said to be besides the covenant made in Horeb; for, though the covenant was the same, yet it was a new promulgation and ratification of it. It is probable that some now living, though not of age to be mustered, were of age to consent for themselves to the covenant made at Horeb, and yet it is here renewed. Note, Those that have solemnly covenanted with God should take all opportunities to do it again, as those that like their choice too well to change. But the far greater part were a new generation, and therefore the covenant must be made afresh with them, for it is fit that the covenant should be renewed to the children of the covenant.

I.It is usual for indentures to begin with a recital; this does so, with a rehearsal of the great things God had done for them, 1. As an encouragement to them to believe that God would indeed be to them a God, for he would not have done so much for them if he had not designed more, to which all he had hitherto done was but a preface (as it were) or introduction; nay, he had shown himself a God in what he had hitherto done for them, which might raise their expectations of something great and answering the vast extent and compass of that pregnant promise, that God would be to them a God. 2. As an engagement upon them to be to him an obedient people, in consideration of what he had done for them.

II.For the proof of what he here advances he appeals to their own eyes (Deu 29:2): You have seen all that the Lord did. Their own senses were incontestable evidence of the matter of fact, that God had done great things for them; and then their own reason was a no less competent judge of the equity of his inference from it: Keep therefore the words of this covenant, Deu 29:9.

III.These things he specifies, to show the power and goodness of God in his appearances for them. 1. Their deliverance out of Egypt, Deu 29:2, Deu 29:3. The amazing signs and miracles by which Pharaoh was plagued and compelled to dismiss them, and Israel was tried (for they are called temptations) whether they would trust God to secure them from, and save them by, those plagues. 2. Their conduct through the wilderness for forty years, Deu 29:5, Deu 29:6. There they were led, and clad, and fed, by miracles; though the paths of the wilderness were not only unknown but untrodden, yet God kept them from being lost there; and (as bishop Patrick observes) those very shoes which by the appointment of God they put on in Egypt, at the passover, when the were ready to march (Exo 12:11), never wore out, but served them to Canaan: and though they lived not upon bread which strengthens the heart, and wine which rejoices it, but upon manna and rock-water, yet they were men of strength and courage, mighty men, and able to go forth to war. By these miracles they were made to know that the Lord was God, and by these mercies that he was their God. 3. The victory they had lately obtained of Sihon and Og, and that good land which they had taken possession of, Deu 29:7, Deu 29:8. Both former mercies and fresh mercies should be improved by us as inducements to obedience.

IV.By way of inference from these memoirs,

1.Moses laments their stupidity: Yet the Lord has not given you a heart to perceive, Deu 29:4. This does not lay the blame of their senselessness, and sottishness, and unbelief, upon God, as if they had stood ready to receive his grace and had begged for it, but he had denied them; no, but it fastens the guilt upon themselves. "The Lord, who is the Father of spirits, a God in covenant with you, and who had always been so rich in mercy to you, no doubt would have crowned all his other gifts with this, he would have given you a heart to perceive and eyes to see if you had not by your own frowardness and perverseness frustrated his kind intentions, and received his grace in vain." Note, (1.) The hearing ear, the seeing eye, and the understanding heart, are the gift of God. All that have them have them from him. (2.) God gives not only food and raiment, but wealth and large possessions, to many to whom he does not give grace. Many enjoy the gifts who have not hearts to perceive the giver, nor the true intention and use of the gifts. (3.) God's readiness to do us good in other things is a plain evidence that if we have not grace, that best of gifts, it is our own fault and not his; he would have gathered us and we would not.

2.Moses charges them to be obedient: Keep therefore, and do, Deu 29:9. Note, We are bound in gratitude and interest, as well as duty and faithfulness, to keep the words of the covenant.

And I have led you forty years in the wilderness,.... From the time of their coming out of Egypt unto that day, which though not quite complete, is given as a round number. Eupolemus (d), an Heathen writer, confirms this date of the ministry of Moses among the Israelites; he says, Moses performed the office of a prophet forty years:

your clothes are not waxen old upon you: were not worn out; all those forty years they had been in the wilderness, they had never wanted clothes fitting for them, according to their age and stature, and which decayed not; See Gill on Deu 8:4,

and thy shoe is not waxen old upon thy foot; which were necessary to wear in travelling, and especially in a rugged wilderness; and yet, thought they had been always in use during so long a time, were not worn out, which was really miraculous; See Gill on Deu 8:4.

(d) Apud Euseb. Praepar. Evangel. l. 9. c. 30. p. 447.

Moses called unto all Israel, . . . Ye have seen all that the Lord did, &c.--This appeal to the experience of the people, though made generally, was applicable only to that portion of them who had been very young at the period of the Exodus, and who remembered the marvellous transactions that preceded and followed that era. Yet, alas! those wonderful events made no good impression upon them (Deu 29:4). They were strangers to that grace of wisdom which is liberally given to all who ask it; and their insensibility was all the more inexcusable that so many miracles had been performed which might have led to a certain conviction of the presence and the power of God with them. The preservation of their clothes and shoes, the supply of daily food and fresh water--these continued without interruption or diminution during so many years' sojourn in the desert. They were miracles which unmistakably proclaimed the immediate hand of God and were performed for the express purpose of training them to a practical knowledge of, and habitual confidence in, Him. Their experience of this extraordinary goodness and care, together with their remembrance of the brilliant successes by which, with little exertion or loss on their part, God enabled them to acquire the valuable territory on which they stood, is mentioned again to enforce a faithful adherence to the covenant, as the direct and sure means of obtaining its promised blessings.
