(26) Cursed be he that confirmeth not all the words of this law to do them.--"Here he sums up the whole Law, all of it, and they took it upon them with a curse and an oath" (Rashi). From this verse St. Paul also reasons that "as many as are of the works of the law are under a curse." For no man can do all of them. And therefore it is impossible to secure the blessing of Gerizim except through Him who bare the curse of Ebal. "Christ hath redeemed us from the curse of the law, being made a curse for us, as it is written, cursed is every one that hangeth on a tree." In all these curses the verb is wanting. "Cursed is he," would be a more correct translation in modern English. These curses are not imprecations so much as declarations of fact.

27:11-26 The six tribes appointed for blessing, were all children of the free women, for to such the promise belongs, Ga 4:31. Levi is here among the rest. Ministers should apply to themselves the blessing and curse they preach to others, and by faith set their own Amen to it. And they must not only allure people to their duty with the promises of a blessing, but awe them with the threatenings of a curse, by declaring that a curse would be upon those who do such things. To each of the curses the people were to say, Amen. It professed their faith, that these, and the like curses, were real declarations of the wrath of God against the ungodliness and unrighteousness of men, not one jot of which shall fall to the ground. It was acknowledging the equity of these curses. Those who do such things deserve to fall, and lie under the curse. Lest those who were guilty of other sins, not here mentioned, should think themselves safe from the curse, the last reaches all. Not only those who do the evil which the law forbids, but those also who omit the good which the law requires. Without the atoning blood of Christ, sinners can neither have communion with a holy God, nor do any thing acceptable to him; his righteous law condemns every one who, at any time, or in any thing, transgresses it. Under its awful curse we remain as transgressors, until the redemption of Christ is applied to our hearts. Wherever the grace of God brings salvation, it teaches the believer to deny ungodliness and wordly lusts, to live soberly, righteously, and godly in this present world, consenting to, and delighting in the words of God's law, after the inward man. In this holy walk, true peace and solid joy are to be found.Cursed be he that confirmeth not all the words of this law to do them,.... That is, who does not perfectly perform all that the law requires, and continues to do so; for the law requires obedience, and that perfect and constant, and in failure thereof curses, in proof of which the apostle produces this passage; see Gill on Galatians 3:10, for the reconciliation of these Scriptures, as to what seeming difference there is between them:

and all the people shall say, Amen; See Gill on Deuteronomy 27:15; See Gill on Deuteronomy 27:16.
