Revelation 13:16-18 And he causes all, small and great, both rich and poor, both free and bond, that they may give them a mark on their right hand, or on their forehead:

Godbey⁽ⁱ⁾ ¹⁶ And he causes all, small and great, both rich and poor, both free and bond, that they may give them a mark on their right hand, or on their forehead: ¹⁷ that no one may be able to buy or sell, except the one having the mark, the name of the beast, or the number of his name. ¹⁸ Here is wisdom. Let the one having understanding count the number of the beast: for it is the number of a man. And his is, Six hundred and sixty-six.
