The false prophet is not any sort of king. The false prophet is who will instigate the requirement that everyone take the mark, name, or number of the name of the beast king in order to buy or sell. Revelation 13:16-17.
A mountain does not die and come back to life.
Revelation 13:14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
Did you miss the following verse about the beast king??
Rev 17:8
8 The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
KJV
What did Lord Jesus just show you back in the Revelation 12:3-4 verses? He revealed that Lucifer rebelled originally using a kingdom that had seven heads, ten horns, but only seven crowns. That old beast kingdom Lucifer rebelled with, and Lucifer as beast king
WAS.
Then what did God do to end Lucifer's original rebellion in the old world? God ended that time and Lucifer fell as lightening to the earth, and his beast king role that
WAS, then became
IS NOT.
Then what happened next. God setup this present world earth age for His Son to be born in the flesh and die on the cross for the remission of the sins of those who believe, to defeat the devil. And to test those at the END of this world who have believed on Jesus, God is allowing Satan to play beast king once again like he did of old, and then Satan will be
YET IS.
So note the phrase above,
"... and shall ascend out of the bottomless pit, and go into perdition:". That is about Satan when he comes at the end of this world to play the false-Messiah in Jerusalem. He will exalt himself in place of God, performing miracles, etc., in plain sight, upon the earth.
