Revelation 17:4-6

Revelation 17:4-6 (KJV)
4 And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication:
5 And upon her forehead was a name written, Mystery, Babylon The Great, The Mother Of Harlots And Abominations Of The Earth.
6 And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration.

The Great Whore

In this vision, John could see that judgement was poured out upon this woman in purple and scarlet, of which sat upon a scarlet beast.

Revelation 17:12-14

Revelation 17:12-14 (KJV)
12 And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.
13 These have one mind, and shall give their power and strength unto the beast.
14 These shall make war with the Lamb, and the Lamb shall overcome them: for he is Lord of lords, and King of kings: and they that are with him are called, and chosen, and faithful.
