I posted this under a thread on clues to dating Revelation--since it fits here I'll copy and paste here as well.
One verse in Revelation provides one good possible clue to the time it was written.
Rev 17:8 HCSV
The beast that you saw was, and is not, and is about to come up from the abyss and go to destruction. Those who live on the earth whose names were not written in the book of life from the foundation of the world will be astounded when they see the beast that was, and is not, and will be present [again].
Nero ruled from 54 - 68 AD. The Roman campaign to put down the Jewish rebellion started in 67, but when Nero committed suicide civil war broke out in Rome and Vespasian who had been leading the campaign and was at Jerusalem withdrew to attend to the unsettled situation in Rome. Rome went through three rulers in a years time before Vespasian consolidated power and became the new ruler. Then he dispatched his son Titus back to Jerusalem to finish the job there.
During his departure the Zealots thought they had beaten off the Romans and were unpleasantly surprised to see them return to finish the job.
This would provide fulfillment of the "will be astounded when they see the beast that was, and is not, and will be present [again]."
Was: The initial Roman movement against Jerusalem by Vespasian.
and is not: Vespasian's leaving Jerusalem.
and will be present again: Titus returns to finish the job
Simple, straight forward, and historically accurate interpretation for dating the writing of Revelation--This could mean Revelation was written during the lull between the Roman campaigns against Jerusalem. They were there, they are not there now and they will be there again.
Or given that all that precedes this verse in the first 16 chapters it most likely simply dates Revelation before 67 AD and John's vision was describing the coming and going and coming again of the Roman's campaigning against Judea/Jerusalem.
Thoughts any one?
Another excellent post IMO; I believe it's a very viable rendering of a difficult to understand passage. I've saved it to file.
You said:
The Roman campaign to put down the Jewish rebellion started in 67.....
Actually it was sometime late in the year AD 66, that Cestius Gallus, [Roman] Governor of Syria and Commander of Roman forces, marched his army into Judea in an attempt to quell the revolts. Vespasian arrived with his forces the following year.
Question for you or anyone else:
And the beast that was, and is not, is himself also an eighth, and is of the seven; and he goeth into perdition. Rev 17:11
What/who is the eighth beast?
