Revelation 17:10-12

Amplified Bible

¹⁰ and they are seven kings: five of whom have fallen, one exists and is reigning; the other [the seventh] has not yet come, and when he does come, he must remain a little while. ¹¹ And the beast that [once] was but is not, is himself also an eighth king and is one of the seven, and he goes to destruction (perdition). ¹² The ten horns that you saw are ten kings who have not yet received a kingdom, but [together] they receive authority as kings for a single hour [for a common purpose] along with the beast.^(A)
