Revelation 13:15-17

WPNT(i) 15 And it was granted to him to give breath to the image of the Beast, so that the image of the Beast should actually speak, and should cause as many as would not worship the image of the Beast to be killed. 16 And he causes everyone—both small and great, both rich and poor, both free and slave—to receive marks on their right hand or on their foreheads, 17 so that no one would be able to buy or sell who does not have the mark, the name of the Beast or the number of his name.
