Revelation 17:10-13

17:10 five have fallen; one is, and the other has not yet come, but whenever he does come, he must remain for only a brief time. 17:11 The beast that was, and is not, is himself an eighth king and yet is one of the seven, and is going to destruction. 17:12 The ten horns that you saw are ten kings who have not yet received a kingdom, but will receive ruling authority as kings with the beast for one hour. 17:13 These kings have a single intent, and they will give their power and authority to the beast.
