Revelation 17:8; Revelation 17:11

8 The 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.

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