This is where we get the 666 from in the Book of Revelation.
Revelation 13:18 (NASB)
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 [a]six hundred and sixty-six.
[a]One early ms reads 616
Is there anything to support this interpretation? If so, what would the implications be?

16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
