Revelation 17:9-11

“This calls for wisdom and understanding. The seven heads are seven hills, on which the woman sits. They are also seven kings: five of them have fallen, one still rules, and the other one has not yet come; when he comes, he must rule only a little while. And the beast that was once alive, but lives no longer, is itself an eighth king who is one of the seven and is going off to be destroyed.
