So Cesar Nero is going to resurrect soon ?

Aramaic and Hebrew did not have vowels in the first century, so words were spelled with consonants. There were different ways one could spell words (in the absence of Webster's dictionary), and one spelling of "Nero Caesar" (or "Caesar Nero") was NRWN QSR.
[blockquote]
Nun = 50
Resh = 200
Waw = 6
Nun = 50
Qop = 100
Samekh = 60
Resh = 200
TOTAL = 666
[/blockquote]
Now, there's lotsa folks who have names that add up to 666, so why should one be confident that
the emperor Nero was who St. John/God had in mind in the book of Revelation?
Well, in Revelation the beast is described as a leader who demands to be worshipped as a god and who persecutes Christians? Any of St. John's contemporaries fit that bill? Yep: Nero.
Any reason we should think that it would
be one of St. John's contemporaries? Yep, again: At its beginning and its end, the book stresses it deals with what will happen "soon" (Rev. 1:1, 22:6).
Anything else?
Yep the third: Another spelling of "Nero Caesar" in Aramaic(/Hebrew) is NRW QSR, which leaves off a nun (50), resulting in the total number 616 instead of 666.
It turns out that some early manuscripts of Revelation record the beast's number as 616 rather than 666.
