Revelation 17:7-13

And the angel said to me, Why hast thou wondered? I will tell thee the mystery of the woman, and of the beast which carries her, which has the seven heads and the ten horns. The beast which thou sawest was, and is not, and is about to come up out of the abyss and go into destruction: and they who dwell on the earth, whose names are not written from the founding of the world in the book of life, shall wonder, seeing the beast, that it was, and is not, and shall be present. Here is the mind that has wisdom: The seven heads are seven mountains, whereon the woman sits. And there are seven kings: five have fallen, one is, the other has not yet come; and when he comes he must remain only a little while. And the beast that was and is not, he also is an eighth, and is of the seven, and goes into destruction. And the ten horns which thou sawest are ten kings, which have not yet received a kingdom, but receive authority as kings one hour with the beast. These have one mind, and give their power and authority to the beast.
