Further update on the Mark.
 
Re 13:16
And he causeth all, both small and great *, rich and poor *, free and bond, to receive a mark in their right hand *, or in their foreheads:

Re 13:17
And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.

Re 14:9
And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,

Re 14:11
And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
