Revelation 17:7, 9-13

But the angel said to me, “Why are you so astonished? I will reveal to you the mystery of the woman, and of the wild beast with seven heads and ten horns that carries her.

“This requires a mind that has wisdom to interpret: The seven heads of the beast are seven mountains the woman sits upon; they are also seven kings. Five kings have fallen, one is, and the other has not yet come—and when he comes he must remain only a little while. The wild beast that was but now is not represents an eighth king who is from one of the seven, and he is going to destruction. “The ten horns that you saw represent ten kings who have not yet received a kingdom, but they and the wild beast are destined to receive authority as kings for a short reign of one hour. They are united in yielding their power and authority to the wild beast.
