Isa 66:15 For, behold, the LORD will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire.
Isa 66:16 For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many.
Isa 66:17 They that sanctify themselves, and purify themselves in the gardens behind one tree in the midst, eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith the LORD.
This is similar to the account in Revelation
Rev 16:15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
Rev 16:16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
Rev 16:17 And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.
Rev 16:18 And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great.
Rev 16:19 And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath.
Rev 16:20 And every island fled away, and the mountains were not found.
Rev 16:21 And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.
Rev 17:1 And there came one of the seven angels which had the seven vials, and talked with me, saying unto me, Come hither; I will show unto thee the judgment of the great whore that sitteth upon many waters:
Rev 17:2 With whom the kiings of the earth have committed fornication, and the inhabitants of the earth have been made drunk with the wine of her fornication.
Isa 66:18 For I know their works and their thoughts: it shall come, that I will gather all nations and tongues; and they shall come, and see my glory.
When the Lord comes back to Jerusalem, the armies of the nation shall be destroyed with those practicing false religions, spiritual fornications under the trees. Evil will be separated from the remnant of God.
Isa 66:19 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 Gentiles.
Missionaries will be sent to the nations, to Tarshish (Spain, France and Italy), Pul and Lud, probably represent Africa. Tubal is the region of Russia and Javan is Greece as well as the far off lands. Although these lands had been evangelized in the past, they may have fallen away, as predicted in the time of the antichrist. His time will be over at the appearing of the Lord. In Europe and even in the United States, there is a spirit of antichrist and once great churches are now empty. Always there is a remnant, even in great compromising churches who no longer preach the gospel. When the Lord comes all will hear of his glory. We now are to preach the glory of the Lord, it is our Great Commission.
Mat 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
If we are raptured, there will be almost no one to tell the nations of the glory of the Lord, until the LORD commissions the 144,000 Jews from the twelve tribes.
Rev 7:2 And I saw another angel ascending from the east, having the seal of the living God: and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea,
Rev 7:3 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.
Rev 7:4 And I heard the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel.
Isa 66:20 And they shall bring all your brethren for an offering unto the LORD out of all nations upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts, to my holy mountain Jerusalem, saith the LORD, as the children of Israel bring an offering in a clean vessel into the house of the LORD.
Isa 66:21 And I will also take of them for priests and for Levities, saith the LORD.
An offering of living souls as in Romans 12.
Rom 12:1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
Rom 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
From those saved Jews and Gentiles shall come priests and Levites, servants of the LORD.

Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Rev 21:3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.
Rev 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
Isa 66:23 And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
The priests and Levites of old were to prepare for and keep the sabbaths and new moons. Some of these early forms of worship may be practiced during the Millennium as a remembrance and as a fulfillment.
1 Chr 23:31 And to offer all burnt sacrifices unto the LORD in the sabbaths, in the new moons, and on the set feasts, by number, according to the order commanded unto them, continually before the LORD:
1 Chr 23:32 And that they should keep the charge of the tabernacle of the congregation, and the charge of the holy place, and the charge of the sons of Aaron their brethren, in the service of the house of the LORD.
Jesus is the substance of the holy days. He is LORD of the Sabbath.
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
No longer will worship be a shallow ritual, but all will worship God from a heart filled with His Spirit and His truth in His presence.
Isa 66:24 And they shall go forth, and look upon the carcases of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorring unto all flesh.
As the citizens of Nazi Germany were to look upon the mass graves and the pitiful condition of the Jewish prisoners, so in the time of Christ's return will the nations look upon the millions of slain in Armageddon. Those in Christ shall live forever in the coming new heaven, but those who oppose him will be cast into the lake of fire, where the worm dieth not.
Mark 9:44 Where their worm dieth not, and the fire is not quenched.
Rev 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
Rev 20:14 And death and hell were cast into the lake of fire. This is the second death.Rev 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
Rev 21:5 And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
Rev 21:6 And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
Rev 21:7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
This concludes our study of Isaiah, 66 books as there are 66 books of the Bible. They are to show us our need to obey God and to follow him until we are reconciled to God. The end result of our journey will be heaven or hell. We are warned throughout the Bible to follow God, to only fear God, to stay the course, for it is in preparation for eternity. May our life count for good in His purpose and may our faith and obedience bring us eternal life in Christ Jesus, King of Kings and Lord of Lords.
