In reply to your 11/21 post can it refer to both? (fivedoves.com) the beast in Rev. 13 is both a king and a kingdom, but it is the king (beast) that receives the mortal deadly wound that is healed.
The following verses Daniel 7:17 & 23 answers the question for us:
Daniel 7:17, "These great beasts, which are four, are four kings, which shall arise out of the earth."
Daniel 7:23, "Thus he said, The fourth beast shall be the fourth kingdom upon earth, which shall be diverse from all kingdoms, and shall devour the whole earth, and shall tread it down, and break it in pieces."
