Revelation 13:16-1821st Century King James Version
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand or in their foreheads,
17 that no man might buy or sell, save he that had the mark or the name of the beast or the number of his name.
18 Here is wisdom: Let him that hath understanding count the number of the beast, for it is the number of a man; and his number is six hundred threescore and six.
