The Bible states that the number is the number of man before it says any thing else about the number what do you think it means.
My thoughts are:
Since man was created on the 6th day of the week could it mean a series of fridays and the other one with one in the middle being the day of the new creation of man in christ indicating friday and sunday there by we get fri.fri fri 666 and fri.sun.fri. 616. This indicationg the beast and the prostitute that rides the scarlet beast in revelations. Does it also indicate the false sabbath of the muslims and christians understood by the Jewish man who wrote these numbers in revelations.
