Revelation 17:9-11

“You need a wise mind to understand this. The seven heads on the beast are seven mountains where the woman sits. And they are seven kings. Five of the kings have already been destroyed, one of the kings lives now, and another has not yet come. When he comes, he must stay a short time. The beast that was once alive, but is not alive now, is also an eighth king. He belongs to the first seven kings, and he will go away to be destroyed.
