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 (Deut. 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 (Deut. 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, Deut. 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, Deut. 29:2, 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, Deut. 29:5, 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 (Exod. 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, Deut. 29:7, 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, Deut. 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, Deut. 29:9. Note, We are bound in gratitude and interest, as well as duty and faithfulness, to keep the words of the covenant.
