Revelation 17:10, 12, 16-17

There are also seven kings. Five have fallen, one is, and the other has not yet come. And when he comes, he must continue a short time.

“The ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast.

And the ten horns which you saw on the beast, these will hate the harlot, make her desolate and naked, eat her flesh and burn her with fire. For God has put it into their hearts to fulfill His purpose, to be of one mind, and to give their kingdom to the beast, until the words of God are fulfilled.
