Revelation 17:8-11

8The beast, which you saw, once was, now is not, and yet will come up out of the Abyss and go to its destruction. The inhabitants of the earth whose names have not been written in the book of life from the creation of the world will be astonished when they see the beast, because it once was, now is not, and yet will come. 9“This calls for a mind with wisdom. The seven heads are seven hills on which the woman sits. 10They are also seven kings. Five have fallen, one is, the other has not yet come; but when he does come, he must remain for only a little while.

11The beast who once was, and now is not, is an eighth king. He belongs to the seven and is going to his destruction.
