“Of this Jerusalem the former one is an image-that Jerusalem of the former earth in which the righteous are disciplined beforehand for incorruption and prepared for salvation. And of this tabernacle Moses received the pattern in the mount; and nothing is capable of being allegorized, but all things are stedfast, and true, and substantial, having been made by God for righteous men's enjoyment. For as it is God truly who raises up man, so also does man truly rise from the dead, and not allegorically, as I have shown repeatedly. And as he rises actually, so also shall he be actually disciplined beforehand for incorruption, and shall go forwards and flourish in the times of the kingdom, in order that he may be capable of receiving the glory of the Father. Then, when all things are made new, he shall truly dwell in the city of God. For it is said, "He that sitteth on the throne said, Behold, I make all things new. And the Lord says, Write all this; for these words are faithful and true. And He said to me, They are done." And this is the truth of the matter.”

“And he that sat upon the throne said,.... By whom is meant, either God the Father, who is often represented in this book as sitting on the throne, and as distinguished from Christ the Lamb; see Rev 4:2 Rev 5:13 and who may seem the more to be intended, since he is by adopting grace the God and Father of his people, and they are his sons and daughters; or rather Christ, who not only is set down on the same throne with his Father, but has a throne of his own, called the throne of the Lamb, and was seen upon one by John in the preceding vision, Rev 20:11 which though in order of time will be after this, yet in the order of the visions was seen before; and especially since the person on the throne speaking, calls himself the Alpha and Omega, the beginning and the end, as Christ does in Rev 1:8 and seeing he it is that gives to thirsty souls of the water of life, Joh 7:37 and makes promises to the overcomer so largely and frequently in Rev 2:7. He addresses John, and delivers the following things to him, behold, I make all things new; which is to be understood not of the renovation of persons at conversion, when a new heart and spirit are given, and men are made wholly new creatures; for this is the work of the Spirit, and which is done daily, and is not peculiar to any particular period of time; nor of the renewing of the church state at the beginning of the Gospel, when the Jewish church state and ordinances waxed old, and vanished away, and a new covenant took place, a new and living way was opened, and new ordinances appointed, since all this was before John had this vision; nor was there any need of it to represent it to him; but of the making of the new heaven, and the new earth, which Christ ascribes to himself and of his forming his church anew, making it a new Jerusalem, bestowing new glories upon his people, both in soul and body, and so presenting them to himself a glorious church; and of the new administration of his kingdom in a very singular and glorious manner; so that it respects a new people, a new habitation, and a new manner of ruling over them; all which is his own doing, and is marvellous; and because it is a matter of great importance, and is wonderful and certain, therefore a "behold" is prefixed to it; see Isa 43:19. The Jews say (z), that the holy blessed God will make ten things new in the future state, or world to come; the first is, he will enlighten the world; (See Rev 21:11) the second is, he will bring living water out of Jerusalem; (see Rev 21:6) the third is, he will make trees to bring forth their fruit every month; (see Rev 22:2) and the fourth is, all the waste places shall be built, even Sodom and Gomorrha; the fifth is, Jerusalem shall be built with sapphire stone; (see Rev 21:19) the sixth is, the cow and the bear shall feed; the seventh is, a covenant shall be made between Israel, and the beasts, fowls, and creeping things; the eighth is, there shall be no more weeping and howling in the world; the ninth is, there shall be no more death in the world; the tenth is, there shall no more be sighing, and groaning, and sorrow in the world; see Rev 21:4. And he said unto me, write; what John had seen, and Christ had said, and was about to say; and particularly what concerned the renewing of all things, the whole being a matter of moment, and worth noting and taking down in writing, that it might be on record for saints to read, and receive comfort and advantage from; and to denote the certainty of it, as well as to show that it was a clear point, and to be known, whereas, when it was otherwise, he was bid not to write; see Rev 1:11. for these words are true and faithful; both what he had said, and was about to say; they were "true", because they came from God, who cannot lie, and "faithful", because they would be punctually and exactly fulfilled; see Rev 19:9. The Syriac version adds, they are God's, and so the Arabic version. (z) Shemot Rabba, sect. 15. fol. 101. 3.”

“Behold, I make all things new - As the creation of the world at the beginning was the work of God alone, so this new creation. These words are true and faithful - Truth refers to the promise of these changes; faithfulness, to the fulfillment of these promises.”

“The text is in the positive degree. The order of the words is inverted in G. P. The Vulgate is supported by the Alexandrian and Vatican manuscripts, and is followed by Baumgarten-Crusius.”

“sat--Greek, "sitteth." all things new--not recent, but changed from the old (Greek, "kaina," not "nea"). An earnest of this regeneration and transfiguration of nature is given already in the regenerate soul. unto me--so Coptic and ANDREAS. But A, B, Vulgate, and Syriac omit. true and faithful--so ANDREAS. But A, B, Vulgate, Syriac, and Coptic transpose, "faithful and true" (literally, "genuine").”

“And he said. As if he said: Write whatever has been shown to you concerning this renewal. This was done for the benefit of those present, for whom I have been commanded to write these things. Write: for these, etc. Commanding him to write and to announce to others, he adds an exhortation, that all may labour to belong to this renewal.”
