The third woe is the 7th Trumpet and the destruction that accompanies it at the climactic second coming.
Revelation 11:12 says, “And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them. And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven. The second woe is past (the great battle); and, behold, the third woe (the last trump – the second coming of the Lord Jesus Christ) cometh quickly.”
Verses 15 records the ushering in of eternity, we learn, “And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever. Christ at this juncture has put down all rebellion and has finally ushered in His eternal reign.”
Your timing is off. You missed the change in narrative.
Revelation 9:12
12 One woe is past; and, behold, there come two woes more hereafter.
13 And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,
The 5th angel is the first woe.
The 6th angel is the second woe.
Now we have an interruption. There are 7 Thunders. Not part of the 3 woes at all. Chapter 10 is the 7 Thunders. Then John explains what is going to happen in the 3rd woe, the 7th Trumpet. The first thing explained is all OT prophets are fulfilled in the sounding of the 7th Trumpet that has a sound that will last days, not a single short blast. Gabriel in Daniel 9:27 claims 1 week of days. In the midst of this week is the 3rd woe. In the midst of the 7th Trumpet sounding is the third woe. But when the Trumpet stops, all will be fulfilled. The 70th week will be fulfilled. Gabriel is more than likely the archangel blowing the 7th Trumpet.
The next thing mentioned about the 7th Trumpet is the temple is measured. There is a temple during the 7th Trumpet. It is measured, and Gentiles trod in this temple (the courtyard) 42 months, during the sound of the 7th Trumpet. Also at this same time for 1260 days the 2 witnesses will be a thorn in the side of these Gentiles and Satan during the sounding of the 7th Trumpet. Now we see an earthquake at the end of these 1260 days and the end of the 42 months. The same earthquake at the 7th vial.
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.
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.
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.
The 2 witnesses ascended right before this earthquake, all during the sound of the 7th Trumpet. This is the third woe. All of the above.
The third woe has to end so the 7th Trumpet can end the 70 weeks to usher in the promises of Daniel 9:24. Gabriel was the messenger to tell Daniel what would happen. Fitting that when it does happen, Gabriel will be sounding the 7th Trumpet.
Now chapter 11 and the 7th Trumpet. It is not after the 2 witnesses, because chapter 10 was that angel (Gabriel) now telling John about the sounding of the 7th Trumpet. His message will be complete as given to Daniel. Chapter 12 places the dragon into the 42 months, with a brief historical background. With the explanation out of the way Revelation 11:14 picks up the 3rd woe narrative, left off before the 7 Thunders interrupted the woes.
14 The second woe is past; and, behold, the third woe cometh quickly.
So it reads:
12 One woe is past; and, behold, there come two woes more hereafter.
13 And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,
14 The second woe is past; and, behold, the third woe cometh quickly.
Verse 14 in chapter 11 picks up the narrative that was interrupted. The 2 witnesses have the same time period as Satan and the 42 months. There is not a 4th woe and an 8th Trumpet for Armageddon. Satan's time, the 7 vials, and Armageddon after the major earthquake are the 3rd woe. They are the desolation that splits the week of days of the sound of the 7th Trumpet.
The Lord coming at Armageddon ends the sound of the 7th Trumpet. That is not the Second Coming. The Second Coming is being finalized by the 7th Trumpet. It already happened, and Christ already set up the temple that is measured in chapter 11. Already set up the throne Satan, and the FP take control over when they defeat the saints in chapter 13. The temple has to be set up to be trod under foot by Satan and the Gentiles 42 months.
The 2 witnesses are not the second woe. They are part of the 3rd woe. The 6th Trumpet is the second woe. The Second Coming happened in the 6th Seal, because Christ brought the trump, and the archangel (Gabriel) at the 6th Seal. The 6 Angels sound in judgment along with the 7 Thunders during the final harvest, where all man's works are burned up, and souls are sent to eternal life or eternal damnation. Christ is on earth for the Great Tribulation, after the tribulation of those days in the first 4 Seals. Christ sets up a throne. Ezekiel claims a temple, and John claims that temple is measured. The confirmation of the Covenant by Messiah Prince leads to either Revelation 14 and the winepress during the week of the 7th Trumpet. Or worse case scenario there is a woe instead of the final winepress. If chapter 13 happens, we get 15, 16, and 19. 17 and 18 are just the end of life as we know it. The end of all OT prophecies. Armageddon is the climactic end of the 70th week at 6pm sharp. It is all over, and the Millennium starts. Daylight, Monday morning a resurrection, Revelation 20:4. A new heaven and earth, because: to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. All accomplished at the Cross, but placed on hold until the fulness of the Gentiles was brought into this Atonement.
