Revelation 17:11 in the King James Version
And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.
Context
10 They are seven kings. Five have fallen, the one is, and the other has not yet come. When he comes, he must continue a little while.
11 The beast that was, and is not, is himself also an eighth, and is of the seven; and he goes to destruction.
12 The ten horns that you saw are ten kings who have received no kingdom as yet, but they receive authority as kings with the beast for one hour.
