Revelation 13:16-18 And he causes all, small and great, rich and poor, free and bond, to receive a mark on their right hand, or on their forehead,

Anderson⁽ⁱ⁾ ¹⁶ And he causes all, small and great, rich and poor, free and bond, to receive a mark on their right hand, or on their forehead, ¹⁷ and that no one should be able to buy or sell, but he that had the mark, the name of the beast, or the number of his name. ¹⁸ Here is wisdom. Let him that has understanding, count the number of the beast: for it is the number of a man, and his number is six hundred and sixty-six.
