"Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six," (Rev. 13:18).
666 is the number of the antichrist,,, the end times figure who will arise with the purpose of opposing God and God's people. 666 is the gamatria of the name of the antichrist.
In Greek and Hebrew there are no numeric characters. There are only alpha characters. For example, the letters a, b, c, d, e, f, etc. are alpha characters. The numbers 0, 1, 2, 3, etc., are numeric characters. They are different -- except for the letter "o" and the number "0". When the Greeks wanted to write a number, they used letters for numbers. The Greek letter "alpha" had the numeric equivalent of 1. The next letter "beta" has the numeric equivalent of 2, and so on. (CARM has a chart of the Hebrew and Greek numeric equivalents if you are interested in more information.)
No. Its just a number. Numbers hold no power in and of themselves beyond that which silly humans give them. 666 WILL BE the number of the anti-Christ somehow someday but right now it means nothing so if your credit card number or license plate say 666 then its no biggie other that reactions from silly humans. If a sales reciept rings up to 6.66$ or 666$ again no problems.
I'm possessed by evil demons that torture me while I'm sleepin I keep dreamin of death and I'm hearin people screamin The devils spirit is trapped inside me and I want it out I'm on the couch bleedin to death in a haunted house With both of my wrists slit, I'm lifted up in the air And suspended in animation like someones holdin me thereI feel somebodys cold hand wrappin around my neck while I choke on my own blood that I swallow and drown to death But I found a breath Somehow managed to slip the clutches I nearly blackened out from dizziness and head rushes Trippin over OD bodies of dead lushes Blood stains paint theSatan will be in to see me later to see if I'm interested in being partners
