The verses of interest in these study are the last verses of revelation 13 where we read:
Rev 13:15 And he [lamblike beast] had power to give life unto the image of the beast [leopardlike beast], that the image of the beast should both speak, and CAUSE that as many as would not WORSHIP the image of the beast should be KILLED.
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:
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.
13:18 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 . (emphasis supplied)
Before we looked at the details of these verses we notice that the beast has 4 distinct elements; it has an image, a mark, a name and number of his name(666). Furthermore the mark is what is enforced and is to be received either on the forehead or hand. These four elements are again clearly distinguished in Rev 15:2
Rev 15:2 And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, [and] over the number of his name, stand on the sea of glass, having the harps of God.
So the beast again has a MARK, IMAGE, NAME and NUMBER OF HIS NAME (666). Clearly the mark of the beast IS NOT 666 but 666 is the number of his name!! God’s final warning through the third angel of rev 14 says
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,
14:10 The same shall drink of the wine of the wrath of God,
God’s warning is against THE MARK and this will be our subject of study henceforth. After we study THE MARK we will have a SEPARATE study on this name and the number attached to the name. Be blessed.
