9 Here is the mind which has wisdom. The seven heads are seven mountains on which the woman sits,
10 And are seven kings: five have fallen, one is, the other has not yet come; and when he comes, he must remain a little while.
11 And the beast who was, and is not, he also is the eight, and is of the seven, and goes into destruction.

9 'seven mountains' - The city of Rome is built on "seven mountains". These are signified by the seven heads of the beast on which the prostitute sits.
10 'seven kings' - The "seven kings" are the seven Caesars of the Roman Empire. The first "five have fallen," i.e., they have died unnaturally (Judg. 3:25; 2 Sam. 1:10, 25, 27). They are Julius Caesar, Tiberius, Caligula, Claudius, and Nero, all of whom either were murdered or committed suicide before John wrote this book. The sixth "one", Domitian, who was also murdered, was living when this book was written; therefore it is said of him that he "is". "The other", the seventh, who will be Antichrist, had "not yet come" at that time. "When he comes he must remain a little while" and will be slain and resurrected with the spirit of the fifth, who is Nero, to be the eight.
11 'also' - Antichrist will be the comming seventh Caesar. But he "also is the eight". According to 13:3, Antichrist will be slain and resurrected. In that resurrection, the spirit of Nero (the fifth Caesar) which comes up out of the abyss, will animate the dead body of the seventh Caesar, Antichrist. This one, composed of the fifth and seventh Caesars, is the eight. Hence, he "is of the seven". It is no wonder people marvel at the sight of such an extraordinary being (v. 8).
