The *meaning* of 666 is the same though. Just because it's not explicitly delineated in Revelation doesn't mean its not true. For the ancient hebrews, 6 was the number of imperfection. Hence why the kikes have taken such an affinity to it. 7 was the number of perfection. Hence, why God slated 7 days in the week and rested on the 7th. To say something 3 times was to extremely emphasize it; to perfect it. 3 was the number of completion. Hence why Jesus was 33 years old at the time of His death, and died at approximately 3:00 in the afternoon. To say '666' is to say complete imperfection. Which is why God's number is 777, complete *perfection*.
>Revelation 13 And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy 2 And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion: and **the dragon gave him his power, and his seat, and great authority**.
666 is the number of the beast, who is one of the devils pawns.
Despite being used interchangeably by many, satan and the beast are two separate creatures in the book of revelation.
They are on the same side, though.
