I keep seeing people writing about their discussions regarding 666. In the text it is 600 + 60 + 6, not 6,6,6. If it were 6,6,6 - it would be written in Hebrew as vav,vav,vav. This is completely different and will lead you down an incorrect interpretation. The numbers 600, 60, and 6 could be written in Hebrew as:
Final Mem, Samekh, Vav (600,60,6)
Tav, Resh, Samekh, Vav (400+200, 60,6)
Those are the most common forms. The underlying Hebrew/Aramaic that the text would have been originally written was not mistranslated, but reads correctly as six hundred sixty and six, not as six six six...
This is very important for those trying to understand this prophecy. If you misquote the text, you will fall to a misunderstanding. Indeed, I find people finding demonization around every corner from this error.
