(Rev 13:16-18 NIV) He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, {17} so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name. {18} This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is man's number. His number is 666.
