Revelation 13:15-18

KJ2000(i) 15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. 16 And he causes all, both small and great, rich and poor, free and slave, to receive a mark in their right hand, or in their foreheads: 17 And that no man might buy or sell, except he that had the mark, or 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 three score and six.
