“After these things I saw another angel coming down from heaven, having great authority, and the earth was illuminated with his glory.” Revelation 18:1.
“But the angel said to me, ‘Why did you marvel? I will tell you the mystery of the woman and of the beast that carries her, which has the seven heads and the ten horns. The beast that you saw was, and is not, and will ascend out of the bottomless pit and go to perdition. And those who dwell on the earth will marvel, whose names are not written in the Book of Life from the foundation of the world, when they see the beast that was, and is not, and yet is.’ Here is the mind which has wisdom: The seven heads are seven mountains on which the woman sits. There [They] are also seven kings. Five have fallen, one is, and the other has not yet come. And when he comes, he must continue a short time. And the beast that was, and is not, is himself also the eighth, and is of the seven, and is going to perdition. And the ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast. These are of one mind, and they will give their power and authority to the beast.” Revelation 17:7-13.
“But the angel said to me, ‘Why did you marvel? I will tell you the mystery of the woman and of the beast that carries her, which has the seven heads and the ten horns. The beast that you saw was, and is not, and will ascend out of the bottomless pit and go to perdition. And those who dwell on the earth will marvel, whose names are not written in the Book of Life from the foundation of the world, when they see the beast that was, and is not, and yet is.’” Revelation 17:7-8.
“Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth – to every nation, tribe, tongue, and people – saying with a loud voice, ‘Fear God and give glory to Him, for the hour of His judgment has come; and worship Him who made heaven and earth, the sea and springs of water.’” Revelation 14:6-7.
“Then the fifth angel sounded: And I saw a star fallen from heaven to the earth. And to him was given the key to the bottomless pit. And he opened the bottomless pit, and smoke arose out of the pit like the smoke of a great furnace. And the sun and the air were darkened because of the smoke of the pit.” Revelation 9:1-2.
