StoveBolts, jasonc and Free I will address all three of you at once as I never ask anyone to agree with me and I want to keep this civil between us. This is how I believe by what I read word for word and has nothing to do with any man teaching me.
Isaiah and Ezekiel were given prophecy to speak over the kings of Babylon and Tyre. Isaiah 14 and Ezekiel 28 are both dual references about Satan as he works through the king of Babylon and the king of Tyre being that Satan is a created angel/spirit and the prince of the power of the air, Ephesians 2:2, and walks to and fro in the earth, Job 1:7.
For the reason of their pride and greed, just like Satan, these two kings and their kingdom is destroyed by God just as Satan will be in Rev 20:10. The remnant in Rev 19:21 are the same as the kings of Babylon, Tyre and every king that Satan has and is working through as they have always been kings of a political, economic and false religious system that will be destroyed.
The key words that reference Satan in these two books are Lucifer in Isaiah 14:12 and Eden and anointed cherub Ezekiel 28: 13, 14.
