Revelation 13:15-18

Sawyer(i) 15 And it was given him to give a spirit to the image of the beast, that the image of the beast should both speak, and cause that all who would not worship the image of the beast should be killed. 16 And he caused all, small and great, and rich and poor, and freemen and servants, to receive the mark on their right hand or on their forehead, 17 and that no one should buy or sell unless he had the mark, the name of the beast or the number of his name. 18 Here is wisdom. Let him that has a mind count the number of the beast; for the number is man's. And his number is six hundred and sixty-six.
