Judgment was set, and the books (Dan & Rev) were opened.

Dan 12:4 But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
Dan 12:8 And I heard, but I understood not: then said I, O my Lord, what shall be the end of these things? 9 And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.
Dan 7:9 I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire. 10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened.
Jesus is the Man in Linen in Daniel 12:6 and the Lamb of God in Revelations chapter 5 who unseals the Book that is being unsealed in Revelations chapter 6.
Daniel the prophet himself shut up the words (Pertaining to the vision mentioned in chapters 8 then, verified in chapter 11) Then in the latter days during the time when the events were to take place his book would be opened once again during it's appointed "time of need". The events of Revelations chapter 6 is the second book that was unsealed already by Jesus a long time ago, but Daniel's would remain sealed till the time of the end. The proper understanding of Daniel is the only way possible to understand the who, where and what of Revelations. What was written in Daniel chapter 10 is not historical, but instead it is future just like the "switch" will conclude, and needs to be re-connected back to chapter 12. (where it belongs) This is the Second of the two books mentioned that were opened at the same time in Daniel 7:10. The first book mentioned was Daniels End times Vision in chapters 8-12, (which is actually 3 chapters when the "switch" is applied to the equation) and the second Book starts being unsealed in Revelations chapter 6. It begins in verse 2 with the first Rider of the white horse, and is where Daniel 7:26,8:25 & 11:45 where the King comes to his abrupt end.
In Daniel 10:20-12:1 is where everything takes on a Spiritual dimension, and is where Revelations chapter 9 begins. In Daniel 10:20 it shows Gabriel telling Daniel that when he goes forth to fight the Prince of Persia "in the latter days" the Prince of Grecia will come. This reflects Revelations 9: when the Angel holding the key to the bottomless pit
Rev 9:1 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit. 2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit. 3 And there came out of the smoke locusts upon the earth: 9:11 And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon...
Then in Revelations chapter 11 the whole process is repeated over again, (and is why the Two Witnesses are wearing Sackcloth because of 12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; 13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. 14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. 15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; 16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: 17 For the great day of his wrath is come; and who shall be able to stand?)
Revelations chapter 12 is also a repeat, but it's mentioning what's taking place on Apollyon's adversary Satan who was cast from Heaven, which is just contrary to coming up from the Abyss.
Rev ch 12 begins by telling who the Queen is, (Israel and the Graftee's) then tells what happened in history. then in verse 6 it tells of "the woman" fleeing into the Wilderness where she is nourished (taught) by the Two Witnesses of Rev 11 for the next 3.5 years. So the moment the Jerusalem event takes place they high tail it out of Israel on the first flight. The twelve Brothers will come together again as one in these latter days and it will be of God's own calling. You will all know him, but only after his/their Candlesticks has been lit.
Those in Judaism are supposed to be part of this Bride as well but she isn't anywhere near ready yet, but will be by the time the two prophets arise. In that time the two won't just be a coupla prophets hanging around doing a bunch of prophesying, by that time the people will know who they are because time and events have unmistakably identified them. Then when the people say "show me" the prophets can identify themselves through the lives of those who proceeded this same event in times past, Elijah and Jeremiah.
Not only do they explain their lives and plight in literally dozens of places (list below) but it also supplies all their Instructions on how to take care of the Multitude who will be drawn to them during that time.
When the Cities have been destroyed then they will "know" who Elijah is/was because only he prophesied correctly in the day appointed but was never listened to.
The enemy thinks we will be directly in the center of the US so that's his focal point. What he doesn't realize is its the center of the "population" is where he'll be found so that would take it slightly to the East and slightly to the south and Northwest Arkansas hits that mark. It's also top and center in the Bible belt which is also significant.
Satan knows that we are all the Apple of God's Eye and also knows that Two individuals will rise up and (at least one) of them can identify him in his time. He actually knew where he would arise from and even know his identity in these modern times. What he wouldn't be knowing is his actual name, nor what he looks like. (otherwise he would have "villianized" him long before his time, thus altering Biblical events that's already spoken of him.) Are you seeing the paradox here?
So, here's the conclusion, or at least so far... The Mystery Babylon prophecy is tied to Rev 6:12-17 reflected again in 16:16-20, 16 And he gathered them together into a place called in the Hebrew tongue Armageddon. 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. 20 And every island fled away, and the mountains were not found. then the "entirety" of Rev ch's 17-18.
God bless you one and all Brothers and Sisters because time isn't on our side right now. Repent and get right with the only one who is able to save you in that time, and it isn't going to be the prophet. He will know that it's "all" about Jesus and His glorious triumphant return and setting up His Kingdom here on Earth for the next thousand years, and God's faithful Children will be His Kings and Princes, and they/we will all learn His ways. (and He, which contrary to popular belief is actually the King of Kindness as well.
More to come so don't go away :-) If ye didn't get it from Jodysephus, it isn't Prophecy..

Could this be Jeremiah's IRON PILLAR ?

Also, see how Daniel chapter 7 relates to the end times prophecies of Daniel Ch's 8-12
