Revelation 13:15-17

Revised Standard Version Catholic Edition

¹⁵ and it was allowed to give breath to the image of the beast so that the image of the beast should even speak, and to cause those who would not worship the image of the beast to be slain. ¹⁶ Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, ¹⁷ so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name.
