Revelation 13:15  And there was given to him to give spirit (life) to the image of the beast, that the image of the beast should both speak and cause to be killed as many as would not worship the image of the beast.  16  And he causes all, both small and great, and rich and poor, and free and slave, to be given a mark upon their right hand or upon their foreheads,  17  and that no one should be able to buy or sell except he that has the mark or the name of the beast, or the number of his name.
