“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 forehead: 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. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.” (Revelation 13:16-18 KJV)
“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, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of his holy angels, and the presence of the Lamb:” (Revelation 14:9-10 KJV)
