Revelation 13:15-17

American Standard Version

¹⁵ And it was given unto him to give breath to it, even to the image of the beast, ^[a]that the image of the beast should both speak, and cause that as many as should not ^[b]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.
