Revelation 13:16 And the second beast required all people small and great, rich
and poor, free and slave, to receive a mark on their right hand or on their forehead,
17 so that no one could buy or sell unless he had the mark—the name of the beast
or the number of its name. 18 Here is a call for wisdom: Let the one who has insight
calculate the number of the beast,for it is the number of a man, and that number is 666.
