|Barnes' Notes on the Bible|
And if any man shall take away from the words of the book of this prophecy - If he shall reject the book altogether; if he shall, in transcribing it, designedly strike any part of it out. It is conceivable that, from the remarkable nature of the communications made in this book, and the fact that they seemed to be unintelligible, John supposed there might be those who would be inclined to omit some portions as improbable, or that he apprehended that when the portions which describe antichrist were fulfilled in distant ages, those to whom those portions applied would be disposed to strike them from the sacred volume, or to corrupt them. He thought proper to guard against this by this solemn declaration of the consequence which would follow such an act. The whole book was to be received - with all its fearful truths - as a revelation from God; and however obscure it might seem, in due time it would be made plain; however faithfully it might depict a fearful apostasy, it was important, both to show the truth of divine inspiration and to save the church, that these disclosures should be in their native purity in the possession of the people of God.
God shall take away his part out of the book of life - Perhaps there is here an intimation that this would be most likely to be done by those who professed to be Christians, and who supposed that their names were in the book of life. In fact, most of the corruptions of the sacred Scriptures have been attempted by those who have professed some form of Christianity. Infidels have but little interest in attempting such changes, and but little influence to make them received by the church. It is most convenient for them, as it is most agreeable to their feelings, to reject the Bible altogether. When it said here that "God would take away his part out of the book of life," the meaning is not that his name had been written in that book, but that he would take away the part which he might have had, or which he professed to have in that book. Such corruption of the divine oracles would show that they had no true religion, and would be excluded from heaven. On the phrase "book of life," see the notes on Revelation 3:5.
And out of the holy city - Described in Revelation 21. He would not be permitted to enter that city; he would have no part among the redeemed.
And from the things which are written in this book - The promises that are made; the glories that are described.
Clarke's Commentary on the Bible
If any man shall take away - If any man shall lessen this meaning, curtail the sense, explain away the spirit and design, of these prophecies, God shall take away his part out of the book of life, etc. Thus Jesus Christ warns all those who consider this book to beware of indulging their own conjectures concerning it. I confess that this warning has its own powerful influence upon my mind, and has prevented me from indulging my own conjectures concerning its meaning, or of adopting the conjectures of others. These visions and threatenings are too delicate and awful a subject to trifle with, or even to treat in the most solemn manner, where the meaning is obscure. I must leave these things to time and event, the surest interpreters. No jot or tittle of Christ's word shall fall to the ground; all shall have its fulfillment in due time.
This is termed a revelation, but it is a revelation of symbols; an exhibition of enigmas, to which no particular solution is given, and to which God alone can give the solution.
Gill's Exposition of the Entire Bible
And if any man shall take away from the prophecy of this book,.... As he may be said to do, who denies the authority of this book, which has been done by some, and which the Holy Ghost foresaw; or takes it away from, or denies the reading of it to the people, as the Papists do with respect to the whole Scripture; and who wilfully pervert the sense of it, and will not have the things in it, relating to antichrist, to belong to him.
God shall take away his part out of the book of life; by which is meant eternal election, which is the meaning of the phrase throughout this book, in which whoever are written shall certainly be saved. The worshippers of the beast, or the antichristian party, who are chiefly regarded here, are not written in it, Revelation 13:8 wherefore taking away the part of such, is only taking away that which they seemed to have; see Luke 8:18 and the sense is, that such shall be cast into the lake of fire, which is the second death, and will be the portion of all that are not written in the book of life, Revelation 20:15. The Alexandrian copy, one of Stephens's, and the Complutensian edition, read, "the tree of life"; and so do the Syriac and Ethiopic versions; the sense is the same; see John 15:2 and out of the holy city; the new Jerusalem, before described, a part in which is a right to enter into it through the gates, and possess the glories of it: what is mentioned here is only a seeming one, which wicked men may flatter themselves with; and the meaning is, that such shall never enter into it, and enjoy the happiness of it, but shall ever be without, Revelation 21:27
and from the things which are written in this book; the blessings promised to the overcomers in Revelation 2:7 which such as detract from this book shall have no share in. The Alexandrian copy, with some others, and the Syriac version, leave out the copulative "and", and read "which are written", &c. connecting them with the book of life, and holy city, which are written, and spoken of, in this book. The Ethiopic version connects the words with the holy city, only reading them, "which is written", &c. The Jews say of their Talmud, that nothing is to be added to it, or diminished from it (o).

Geneva Study Bible
And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
People's New Testament
22:19 And if any man shall take away from the words of the book of this prophecy. This could be done by denying, or explaining away the words of prophecy. To do either is a deadly sin. Indeed, to tamper with the Divine word in any way is sinful.
22:18-19 I testify to every one, and c. - From the fulness of his heart, the apostle utters this testimony, this weighty admonition, not only to the churches of Asia, but to all who should ever hear this book. He that adds, all the plagues shall be added to him; he that takes from it, all the blessings shall be taken from him; and, doubtless, this guilt is incurred by all those who lay hinderances in the way of the faithful, which prevent them from hearing their Lord's I come, and answering, Come, Lord Jesus. This may likewise be considered as an awful sanction, given to the whole New Testament; in like manner as Moses guarded the law, Deut 4:2, and Deut 12:32; and as God himself did, Mal 4:4, in closing the canon of the Old Testament.

Scofield Reference Notes
 words  life
Inspiration: Summary. The testimony of the Bible to itself.
(1) The writers affirm, where they speak of the subject at all, they speak by direct divine authority.
(2) They invariably testify that the words, and not the ideas merely, are inspired. The most important passage is 1Cor 2:7-15 which see.
(3) The whole attitude of Jesus Christ toward the Old Testament, as disclosed in His words, both before His death and after His resurrection, confirms its truth and divine origin, and He explicitly ascribes the Pentateuch to Moses.
(4) In promising subsequent revelations after the predicted advent of the Spirit Jn 16:12-15 our Lord prepared the way for the New Testament.
(5) The writers of the New Testament invariably treat the Old Testament as authoritative and inspired. See Scofield Note: "2Pet 1:19". See Scofield Note: "1Cor 2:13".
 life Eternal life, Summary of the teaching:
(1) The life is called "eternal" because it was from the eternity which is past unto the eternity which is to come--it is the life of God revealed in Jesus Christ, who is God Jn 1:4 5:26 1Jn 1:1,2
(2) This life of God, which was revealed in Christ, is imparted in a new birth by the Holy Spirit, acting upon the word of God, to every believer on the Lord Jesus Christ Jn 3:3-15.
(3) The life thus imparted was from the beginning." But the recipient is a "new creation" 2Cor 5:17 Gal 6:15.
(4) The life of God which is the believer is an unsevered part of the life which eternally was, and eternally is, in Christ Jesus--one life, in Him and in the believer--Vine and branches; Head and members 1Cor 6:17 Gal 2:20 Col 1:27 3:3,4 1Jn 5:11,12 Jn 15:1-5 1Cor 12:12-14
Jamieson-Fausset-Brown Bible Commentary
19. book-None of our manuscripts read this. A, B, Aleph, Vulgate, Syriac, and Coptic read, "(take away his part, that is, portion) from the tree of life," that is, shall deprive him of participation in the tree of life.
and from the things-so Vulgate. But A, B, Aleph, Syriac, Coptic, and Andreas omit "and"; then "which are written in this book" will refer to "the holy city and the tree of life." As in the beginning of this book (Re 1:3) a blessing was promised to the devout, obedient student of it, so now at its close a curse is denounced against those who add to, or take from, it.
Matthew Henry's Concise Commentary
22:6-19 The Lord Jesus spake by the angel, solemnly confirming the contents of this book, particularly of this last vision. He is the Lord God faithful and true. Also by his messengers; the holy angels showed them to holy men of God. They are things that must shortly be done; Christ will come quickly, and put all things out of doubt. And by the integrity of that angel who had been the apostle's interpreter. He refused to accept religious worship from John, and reproved him for offering it. This presents another testimony against idolatrous worship of saints and angels. God calls every one to witness to the declarations here made. This book, thus kept open, will have effect upon men; the filthy and unjust will be more so, but it will confirm, strengthen, and further sanctify those who are upright with God. Never let us think that a dead or disobedient faith will save us, for the First and the Last has declared that those alone are blessed who do his commandments. It is a book that shuts out form heaven all wicked and unrighteous persons, particularly those who love and make lies, therefore cannot itself be a lie. There is no middle place or condition. Jesus, who is the Spirit of prophecy, has given his churches this morning-light of prophecy, to assure them of the light of the perfect day approaching. All is confirmed by an open and general invitation to mankind, to come and partake freely of the promises and of the privileges of the gospel. The Spirit, by the sacred word, and by convictions and influence in the sinner's conscience, says, Come to Christ for salvation; and the bride, or the whole church, on earth and in heaven, says, Come and share our happiness. Lest any should hesitate, it is added, Let whosoever will, or, is willing, come and take of the water of life freely. May every one who hears or reads these words, desire at once to accept the gracious invitation. All are condemned who should dare to corrupt or change the word of God, either by adding to it, or taking from it.
Matthew Henry's Whole Bible Commentary
We have here a solemn ratification of the contents of this book, and particularly of this last vision (though some think it may not only refer to the whole book, but to the whole New Testament, yea, to the whole Bible, completing and confirming the canon of scripture); and here, 1. This is confirmed by the name and nature of that God who gave out these discoveries: he is the Lord God, faithful and true, and so are all his sayings. 2. By the messengers he chose, to reveal these things to the world; the holy angels showed them to holy men of God; and God would not employ his saints and angels in deceiving the world. 3. They will soon be confirmed by their accomplishment: they are things that must shortly be done; Christ will make haste, he will come quickly, and put all things out of doubt; and then those will prove the wise and happy men who have believed and kept his words. 4. By the integrity of that angel who had been the apostle's guide and interpreter in these visions; this integrity was such that he not only refused to accept religious adoration from John, but once and again reproved him for it. He who was so tender of the honour of God, and so displeased with what was a wrong to God, would never come in his name to lead the people of God into mere dreams and delusions; and it is a still further confirmation of the sincerity of this apostle that he confesses his own sin and folly, into which he had now again relapsed, and he leaves this his failing on perpetual record: this shows he was a faithful and an impartial writer. 5. By the order given to leave the book of the prophecy open, to be perused by all, that they might labour to understand it, that they might make their objections against it, and compare the prophecy with the events. God here deals freely and openly with all; he does not speak in secret, but calls every one to witness to the declarations here made, v. 10. 6. By the effect this book, thus kept open, will have upon men; those that are filthy and unjust will take occasion thence to be more so, but it will confirm, strengthen, and further sanctify those that are upright with God; it will be a savour of life to some and of death to others, and so will appear to be from God, v. 12. 7. It will be Christ's rule of judgment at the great day; he will dispense rewards and punishments to men according as their works agree or disagree with the word of God; and therefore that word itself must needs be faithful and true. 8. It is the word of him who is the author, finisher, and rewarder of the faith and holiness of his people, v. 13, 14. He is the first and the last, and the same from first to last, and so is his word too; and he will by this word give to his people, who conform themselves to it, a right to the tree of life, and an entrance into heaven; and this will be a full confirmation of the truth and authority of his word, since it contains the title and evidence of that confirmed state of holiness and happiness that remains for his people in heaven. 9. It is a book that condemns and excludes from heaven all wicked, unrighteous persons, and particularly those that love and make lies (v. 15), and therefore can never be itself a lie. 10. It is confirmed by the testimony of Jesus, which is the Spirit of prophecy. And this Jesus, as God, is the root of David, though, as man, his offspring-a person in whom all uncreated and created excellencies meet, too great and too good to deceive his churches and the world. He is the fountain of all light, the bright and the morning star, and as such has given to his churches this morning light of prophecy, to assure them of the light of that perfect day which is approaching. 11. It is confirmed by an open and general invitation to all to come and partake of the promises and privileges of the gospel, those streams of the water of life; these are tendered to all who feel in their souls a thirst which nothing in this world can quench. 12. It is confirmed by the joint testimony of the Spirit of God, and that gracious Spirit that is in all the true members of the church of God; the Spirit and the bride join in testifying the truth and excellency of the gospel. 13. It is confirmed by a most solemn sanction, condemning and cursing all who should dare to corrupt or change the word of God, either by adding to it or taking from it, v. 18, 19. He that adds to the word of God draws down upon himself all the plagues written in this book; and he who takes any thing away from it cuts himself off from all the promises and privileges of it. This sanction is like a flaming sword, to guard the canon of the scripture from profane hands. Such a fence as this God set about the law (Deu. 4:2), and the whole Old Testament (Mal. 4:4), and now in the most solemn manner about the whole Bible, assuring us that it is a book of the most sacred nature, divine authority, and of the last importance, and therefore the peculiar care of the great God.
