Revelation 13:15-18 And there was given to it to give a spirit to the image of the beast, so that the image of the beast might both speak, and might cause as many as would not worship the image of the beast to be killed.

MKJV⁽ⁱ⁾ ¹⁵ And there was given to it to give a spirit to the image of the beast, so that the image of the beast might both speak, and might cause as many as would not worship the image of the beast to be killed. ¹⁶ And it causes all, both small and great, rich and poor, free and bond, to receive a mark on their right hand, or in their foreheads, ¹⁷ even that not any might buy or sell except those having the mark, or the name of the beast, or the number of its name. ¹⁸ Here is the wisdom. Let him having reason count the number of the beast, for it is the number of a man. And its number is six hundred and sixty-six.
