7 "Why are you so amazed?" the angel asked. "I will tell you the mystery of this woman and of the beast with seven heads and ten horns on which she sits. 8 The beast you saw was once alive but isn't now. And yet he will soon come up out of the bottomless pit and go to eternal destruction. And the people who belong to this world, whose names were not written in the Book of Life before the world was made, will be amazed at the reappearance of this beast who had died. 9 "This calls for a mind with understanding: The seven heads of the beast represent the seven hills where the woman rules. They also represent seven kings. 10 Five kings have already fallen, the sixth now reigns, and the seventh is yet to come, but his reign will be brief. 11 "The scarlet beast that was, but is no longer, is the eighth king. He is like the other seven, and he, too, is headed for destruction. 12 The ten horns of the beast are ten kings who have not yet risen to power. They will be appointed to their kingdoms for one brief moment to reign with the beast. 13 They will all agree to give him their power and authority.
14 Together they will go to war against the Lamb, but the Lamb will defeat them because he is Lord of all lords and King of all kings. And his called and chosen and faithful ones will be with him."

Commentary on Revelation 17:7-14
(Read Revelation 17:7-14)
The beast on which the woman sat was, and is not, and yet is. It was a seat of idolatry and persecution, and is not; not in the ancient form, which was pagan: yet it is; it is truly the seat of idolatry and tyranny, though of another sort and form. It would deceive into stupid and blind submission all the inhabitants of the earth within its influence, except the remnant of the elect. This beast was seven heads, seven mountains, the seven hills on which Rome stands; and seven kings, seven sorts of government. Five were gone by when this prophecy was written; one was then in being; the other was yet to come. This beast, directed by the papacy, makes an eighth governor, and sets up idolatry again. It had ten horns, which are said to be ten kings who had as yet no kingdoms; they should not rise up till the Roman empire was broken; but should for a time be very zealous in her interest. Christ must reign till all enemies be put under his feet. The reason of the victory is, that he is the King of kings, and Lord of lords. He has supreme dominion and power over all things; all the powers of earth and hell are subject to his control. His followers are called to this warfare, are fitted for it, and will be faithful in it.
