Revelation 13:15-17

ERV(i) 15 And it was given [unto him] to give breath to it, [even] to the image of the beast, that the image of the beast should both speak, and cause that as many as should not worship the image of the beast should be killed. 16 And he causeth all, the small and the great, and the rich and the poor, and the free and the bond, that there be given them a mark on their right hand, or upon their forehead; 17 and that no man should be able to buy or to sell, save he that hath the mark, [even] the name of the beast or the number of his name.
