text: The Bible doesn't say that 666 is the devil's number, it says it is the "mark of the beast".  Many biblical scholars hypothosize that the book of Revelation wasn't actually talking about future "end times" type stuff, but that it was actually speaking in code about the Roman Empire, that was severely persecuting Christians during the time.  Many believe that 666 actually comes from the Hebrew way of writing people's name in code, and actually stands for the emperor Nero (or maybe Domitian, but that's a debate for people way more academic than me)
