1. If the Greek words "neron Kaiser" are put it into Hebrew letters and given Hebrew numbering:

2. If you add up the number of the first initials of the emperors names in Greek from Julius Caesar to Vespasion you come up with

666. (Emperors were sometimes signified by the number of the first letter of their name).

3. If you abbreviate Domitian's full title (Imperator Comitianus Augustus Germanicus in Latin; Autokrator Kaisar Dometianos Sebastos Gennanilos in Greek) in the same way it was abbreviated on coins of the day, you came up with the required number of 666.

4. etc.

If you ignore the fact that Revelation says this is a human (i.e. literal) number and not a symbolic number then you can come up with all sorts of other meanings for 666. The Problem with doing this is that the text tells you not to, and if you 're going to take Revelation seriously, then listen to what it says. Some of the symbolic meanings you can come up with are:

1. 666 = 3 sixes; six is the number of evil because it falls short of 7, the perfect number. So 666 = "evil, evil, evil".

2. 666 = a triangular number, as opposed to the square numbers of the martyrs and the holy city (7:4 and 21:16). Therefore 666 = hellish (as opposed to heavenly).

3. 666 = all that is left out of the monsters kingdom of 1000 after the destruction of a third by the trumpet plagues. Therefore 666 = the monster's Kingdom.

(The problem with this reasoning is then one is left wondering: what about the fourth destroyed by the horsemen, the tenth of the city destroyed by earthquake? etc.

Conclusion: No one can prove what 666 means. The point is that there are 2 groups of people: those who are God's (and condemned by the world) and those who are Satan's.

Aside: A word about "anti-Christ", a term some use for the beast in chapter 13.

However, it is never used in Revelation. As it appears in the New Testament (Mark 13:6; 2 Thess. 2:3-8; 1 John 2:16, 22) it refers to the one who opposes Christ in all times and places.
