Again, it appears that this is after probation closes, but not at the beginning, I don't think. It begins to get a little fuzzy as to the timing. The time of trouble such as never was is after probation closes. I doubt that Babylon is destroyed immediately, but rather some time after the general plagues are poured out. Not sure though. We are dealing with the transition between Daniel 11 and 12.
Revelation
18:6 Reward her even as she rewarded you, and double unto her double according to her works: in the cup which she hath filled fill to her double.
18:7 How much she hath glorified herself, and lived deliciously, so much torment and sorrow give her: for she saith in her heart, I sit a queen, and am no widow, and shall see no sorrow.
18:8 Therefore shall her plagues come in one day, death, and mourning, and famine; and she shall be utterly burned with fire: for strong [is] the Lord God who judgeth her.
18:9 And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning,
18:10 Standing afar off for the fear of her torment, saying, Alas, alas that great city Babylon, that mighty city! for in one hour is thy judgment come.
18:11 And the merchants of the earth shall weep and mourn over her; for no man buyeth their merchandise any more:
18:12 The merchandise of gold, and silver, and precious stones, and of pearls, and fine linen, and purple, and silk, and scarlet, and all thyine wood, and all manner vessels of ivory, and all manner vessels of most precious wood, and of brass, and iron, and marble,
18:13 And cinnamon, and odours, and ointments, and frankincense, and wine, and oil, and fine flour, and wheat, and beasts, and sheep, and horses, and chariots, and slaves, and souls of men.
18:14 And the fruits that thy soul lusted after are departed from thee, and all things which were dainty and goodly are departed from thee, and thou shalt find them no more at all.
18:15 The merchants of these things, which were made rich by her, shall stand afar off for the fear of her torment, weeping and wailing,
18:16 And saying, Alas, alas, that great city, that was clothed in fine linen, and purple, and scarlet, and decked with gold, and precious stones, and pearls!
18:17 For in one hour so great riches is come to nought. And every shipmaster, and all the company in ships, and sailors, and as many as trade by sea, stood afar off,
18:18 And cried when they saw the smoke of her burning, saying, What [city is] like unto this great city!
18:19 And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas, that great city, wherein were made rich all that had ships in the sea by reason of her costliness! for in one hour is she made desolate.
18:20 Rejoice over her, [thou] heaven, and [ye] holy apostles and prophets; for God hath avenged you on her.
18:21 And a mighty angel took up a stone like a great millstone, and cast [it] into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all.
18:22 And the voice of harpers, and musicians, and of pipers, and trumpeters, shall be heard no more at all in thee; and no craftsman, of whatsoever craft [he be], shall be found any more in thee; and the sound of a millstone shall be heard no more at all in thee;
18:23 And the light of a candle shall shine no more at all in thee; and the voice of the bridegroom and of the bride shall be heard no more at all in thee: for thy merchants were the great men of the earth; for by thy sorceries were all nations deceived.
18:24 And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.
Chapter 19
19:1 And after these things I heard a great voice of much people in heaven, saying, Alleluia; Salvation, and glory, and honour, and power, unto the Lord our God:
19:2 For true and righteous [are] his judgments: for he hath judged the great whore, which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand.
Daniel
11:40 And at the time of the end shall the king of the south push at him: and the king of the north shall come against him like a whirlwind, with chariots, and with horsemen, and with many ships; and he shall enter into the countries, and shall overflow and pass over.
11:41 He shall enter also into the glorious land, and many [countries] shall be overthrown: but these shall escape out of his hand, [even] Edom, and Moab, and the chief of the children of Ammon.
11:42 He shall stretch forth his hand also upon the countries: and the land of Egypt shall not escape.
11:43 But he shall have power over the treasures of gold and of silver, and over all the precious things of Egypt: and the Libyans and the Ethiopians [shall be] at his steps.
11:44 But tidings out of the east and out of the north shall trouble him: therefore he shall go forth with great fury to destroy, and utterly to make away many.
11:45 And he shall plant the tabernacles of his palace between the seas in the glorious holy mountain; yet he shall come to his end, and none shall help him.
Chapter 12
12:1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation [even] to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
