Revelation 13:17-18New King James Version (NKJV) 17 and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name. 18 Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666. What number do you need to open a bank account or start other transactions? Here in the U.S.S.A it's the social security number. Kind of an unusual term; does it give security or is it social? Have we found the 'beast' and it is us?
