18 And I,—their works and their thoughts [are before me]. ... [The time] cometh for the gathering of all nations and tongues; and they shall come, and see my glory. 19 And I will set a sign among them, and I will send those that escape of them unto the nations, to Tarshish, Pul, and Lud, that draw the bow; to Tubal and Javan, to the isles afar off, that have not heard my fame, neither have seen my glory: and they shall declare my glory among the nations. 20 And they shall bring all your brethren out of all the nations as an oblation unto Jehovah, upon horses, and in chariots, and in covered waggons, and upon mules, and upon dromedaries, to my holy mountain, to Jerusalem, saith Jehovah, as the children of Israel bring an oblation in a clean vessel into the house of Jehovah. 21 And I will also take of them for priests [and] for Levites, saith Jehovah. 22 For as the new heavens and the new earth which I will make shall remain before me, saith Jehovah, so shall your seed and your name remain. 23 And it shall come to pass from new moon to new moon, and from sabbath to sabbath, all flesh shall come to worship before me, saith Jehovah.
Matthew Henry's Commentary on Isaiah 66:18-23
Commentary on Isaiah 66:15-24
(Read Isaiah 66:15-24)
A prophetic declaration is given of the Lord's vengeance on all enemies of his church, especially that of all antichristian opposers of the gospel in the latter days. Verses 19,20, set forth the abundance of means for conversion of sinners. These expressions are figurative, and express the plentiful and gracious helps for bringing God's elect home to Christ. All shall be welcome; and nothing shall be wanting for their assistance and encouragement. A gospel ministry shall be set up in the church; they would have solemn worship before the Lord. In the last verse the nature of the punishment of sinners in the world to come is represented. Then shall the righteous and wicked be separated. Our Saviour applies this to the everlasting misery and torment of impenitent sinners in the future state. To the honour of that free grace which thus distinguishes them, let the redeemed of the Lord, with humility, and not without holy trembling, sing triumphant songs. With this affecting representation of the opposite states of the righteous and wicked, characters which include the whole human race, Isaiah concludes his prophecies. May God grant, for Christ's sake, that our portion may be with those who fear and love his name, who cleave to his truths, and persevere in every good work, looking to receive from the Lord Jesus Christ the gracious invitation, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world.
