Revelation 17:10-14

10they are also seven kings, five of whom have fallen, one is, the other has not yet come, and when he does come he must remain only a little while.

11As for the beast that was and is not, it is an eighth but it belongs to the seven, and it goes to destruction.

12And the ten horns that you saw are ten kings who have not yet received royal power, but they are to receive authority as kings for one hour, together with the beast.

13These are of one mind, and they hand over their power and authority to the beast.

14They will make war on the Lamb, and the Lamb will conquer them, for he is Lord of lords and King of kings, and those with him are called and chosen and faithful."
