Who is the 7th King of Revelation 17:10-11?

➥ Revelation 17:9-11
9 This calls for a mind with wisdom: the seven heads are seven mountains on which the woman is seated; 10 they are also seven kings, five of whom have fallen, one is, the other has not yet come, and when he does come he must remain only a little while. 11 As for the beast that was and is not, it is an eighth but it belongs to the seven, and it goes to destruction. 12 And the ten horns that you saw are ten kings who have not yet received royal power, but they are to receive authority as kings for one hour, together with the beast. 13 These are of one mind, and they hand over their power and authority to the beast. 14 They will make war on the Lamb, and the Lamb will conquer them, for he is Lord of lords and King of kings, and those with him are called and chosen and faithful.”

Provides details on “beast that was and is not.”
And I saw a beast rising out of the sea, with ten horns and seven heads, with ten diadems on its horns and blasphemous names on its heads. 2 And the beast that I saw was like a leopard; its feet were like a bear’s, and its mouth was like a lion’s mouth. And to it the dragon gave his power and his throne and great authority. 3 One of its heads seemed to have a mortal wound, but its mortal wound was healed, and the whole earth marveled as they followed the beast. 4 And they worshiped the dragon, for he had given his authority to the beast, and they worshiped the beast, saying, “Who is like the beast, and who can fight against it?”
5 And the beast was given a mouth uttering haughty and blasphemous words, and it was allowed to exercise authority for forty-two months. 6 It opened its mouth to utter blasphemies against God, blaspheming his name and his dwelling,[a] that is, those who dwell in heaven. 7 Also it was allowed to make war on the saints and to conquer them. And authority was given it over every tribe and people and language and nation, 8 and all who dwell on earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain. 9 If anyone has an ear, let him hear:
10 If anyone is to be taken captive, to captivity he goes; if anyone is to be slain with the sword, with the sword must he be slain. Here is a call for the endurance and faith of the saints.

➥ Revelation 13:11-18
11 Then I saw another beast rising out of the earth. It had two horns like a lamb and it spoke like a dragon. 12 It exercises all the authority of the first beast in its presence, and makes the earth and its inhabitants worship the first beast, whose mortal wound was healed. 13 It performs great signs, even making fire come down from heaven to earth in front of people, 14 and by the signs that it is allowed to work in the presence of the beast it deceives those who dwell on earth, telling them to make an image for the beast that was wounded by the sword and yet lived. 15 And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not worship the image of the beast to be slain. 16 Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, 17 so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. 18 This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.

And I saw the beast and the kings of the earth with their armies gathered to make war against him who was sitting on the horse and against his army. 20 And the beast was captured, and with it the false prophet who in its presence had done the signs by which he deceived those who had received the mark of the beast and those who worshiped its image. These two were thrown alive into the lake of fire that burns with sulfur. 21 And the rest were slain by the sword that came from the mouth of him who was sitting on the horse, and all the birds were gorged with their flesh.

Destruction of Great Prostitute Riding the Beast!

17 Then one of the seven angels who had the seven bowls came and said to me, “Come, I will show you the judgment of the great prostitute who is seated on many waters, 2 with whom the kings of the earth have committed sexual immorality, and with the wine of whose sexual immorality the dwellers on earth have become drunk.” 3 And he carried me away in the Spirit into a wilderness, and I saw a woman sitting on a scarlet beast that was full of blasphemous names, and it had seven heads and ten horns. 4 The woman was arrayed in purple and scarlet, and adorned with gold and jewels and pearls, holding in her hand a golden cup full of abominations and the impurities of her sexual immorality. 5 And on her forehead was written a name of mystery: “Babylon the great, mother of prostitutes and of earth’s abominations.” 6 And I saw the woman, drunk with the blood of the saints, the blood of the martyrs of Jesus.

When I saw her, I marveled greatly. 7 But the angel said to me, “Why do you marvel? I will tell you the mystery of the woman, and of the beast with seven heads and ten horns that carries her. 8 The beast that you saw was, and is not, and is about to rise from the bottomless pit and go to destruction. And the dwellers on earth whose names have not been written in the book of life from the foundation of the world will marvel to see the beast, because it was and is not and is to come. 9 This calls for a mind with wisdom: the seven heads are seven mountains on which the woman is seated; 10 they are also seven kings, five of whom have fallen, one is, the other has not yet come, and when he does come he must remain only a little while. 11 As for the beast that was and is not, it is an eighth but it belongs to the seven, and it goes to destruction. 12 And the ten horns that you saw are ten kings who have not yet received royal power, but they are to receive authority as kings for one hour, together with the beast. 13 These are of one mind, and they hand over their power and authority to the beast. 14 They will make war on the Lamb, and the Lamb will conquer them, for he is Lord of lords and King of kings, and those with him are called and chosen and faithful.”

15 And the angel said to me, “The waters that you saw, where the prostitute is seated, are peoples and multitudes and nations and languages. 16 And the ten horns that you saw, they and the beast will hate the prostitute. They will make her desolate and naked, and devour her flesh and burn her up with fire, 17 for God has put it into their hearts to carry out his purpose by being of one mind and handing over their royal power to the beast, until the words of God are fulfilled. 18 And the woman that you saw is the great city that has dominion over the kings of the earth.”

The Fall of Babylon

1 After this I saw another angel coming down from heaven, having great authority, and the earth was made bright with his glory. 2 And he called out with a mighty voice, “Fallen, fallen is Babylon the great! She has become a dwelling place for demons, a haunt for every unclean spirit, a haunt for every unclean bird, a haunt for every unclean and detestable beast. 3 For all nations have drunk the wine of the passion of her sexual immorality, and the kings of the earth have committed immorality with her, and the merchants of the earth have grown rich from the power of her luxurious living.” 4 Then I heard another voice from heaven saying, “Come out of her, my people, lest you take part in her sins, lest you share in her plagues; 5 for her sins are heaped high as heaven, and God has remembered her iniquities. 6 Pay her back as she herself has paid back others, and repay her double for her deeds; mix a double portion for her in the cup she mixed. 7 As she glorified herself and lived in luxury, so give her a like measure of torment and mourning, since in her heart she says, ‘I sit as a queen, I am no widow, and mourning I shall never see.’ 8 For this reason her plagues will come in a single day, death and mourning and famine, and she will be burned up with fire; for mighty is the Lord God who has judged her.” 9 And the kings of the earth, who committed sexual immorality and lived in luxury with her, will weep and wail over her when they see the smoke of her burning. 10 They will stand far off, in fear of her torment, and say, “Alas! Alas! You great city, you mighty city, Babylon! For in a single hour your judgment has come.” 11 And the merchants of the earth weep and mourn for her, since no one buys their cargo anymore, 12 cargo of gold, silver, jewels, pearls, fine linen, purple cloth, silk, scarlet cloth, all kinds of scented wood, all kinds of articles of ivory, all kinds of articles of costly wood, bronze, iron and marble, 13 cinnamon, spice, incense, myrrh, frankincense, wine, oil, fine flour, wheat, cattle and sheep, horses and chariots, and slaves, that is, human souls. 14 “The fruit for which your soul longed has gone from you, and all your delicacies and your splendors are lost to you, never to be found again!” 15 The merchants of these wares, who gained wealth from her, will stand far off, in fear of her torment, weeping and mourning aloud, 16 “Alas, alas, for the great city that was clothed in fine linen, in purple and scarlet, adorned with gold, with jewels, and with pearls! 17 For in a single hour all this wealth has been laid waste.”And all shipmasters and seafaring men, sailors and all whose trade is on the sea, stood far off 18 and cried out as they saw the smoke of her burning, “What city was like the great city?” 19 And they threw dust on their heads as they wept and mourned, crying out, “Alas, alas, for the great city where all who had ships at sea grew rich by her wealth! For in a single hour she has been laid waste. 20 Rejoice over her, O heaven, and you saints and apostles and prophets, for God has given judgment for you against her!” 21 Then a mighty angel took up a stone like a great millstone and threw it into the sea, saying, “So will Babylon the great city be thrown down with violence, and will be found no more; 22 and the sound of harpists and musicians, of flute players and trumpeters, will be heard in you no more, and a craftsman of any craft will be found in you no more, and the sound of the mill will be heard in you no more, 23 and the light of a lamp will shine in you no more, and the voice of bridegroom and bride will be heard in you no more, for your merchants were the great ones of the earth, and all nations were deceived by your sorcery. 24 And in her was found the blood of prophets and of saints, and of all who have been slain on earth.”

Revelation 19:1-10 Heavens Celebrate Babylon’s Destruction! – Time for Marriage of the Lamb!

1 After this I heard what sounded like the roar of a great multitude in heaven shouting: “Hallelujah! Salvation and glory and power belong to our God, 2 for true and just are his judgments. He has condemned the great prostitute who corrupted the earth by her adulteries. He has avenged on her the blood of his servants.” 3 And again they shouted: “Hallelujah! The smoke from her goes up for ever and ever.” 4 The twenty-four elders and the four living creatures fell down and worshiped God, who was seated on the throne. And they cried: “Amen, Hallelujah!” 5 Then a voice came from the throne, saying: “Praise our God, all you his servants, you who fear him, both great and small!” 6 Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting: “Hallelujah! For our Lord God Almighty reigns. 7 Let us rejoice and be glad and give him glory! For the wedding of the Lamb has come, and his bride has made herself ready. 8 Fine linen, bright and clean, was given her to wear.” (Fine linen stands for the righteous acts of God’s holy people.) 9 Then the angel said to me, “Write this: Blessed are those who are invited to the wedding supper of the Lamb!” And he added, “These are the true words of God.” 10 At this I fell at his feet to worship him. But he said to me, “Don’t do that! I am a fellow servant with you and with your brothers and sisters who hold to the testimony of Jesus. Worship God! For it is the Spirit of prophecy who bears testimony to Jesus.”
