Revelation 13:16-18

Bible Text

[16] He causes all, the small and the great, the rich and the poor, and the free and the slave, to be given marks on their right hands, or on their foreheads; [17] and that no one would be able to buy or to sell, unless he has that mark, the name of the beast or the number of his name. [18] Here is wisdom. He who has understanding, let him calculate the number of the beast, for it is the number of a man. His number is six hundred sixty-six.
