Isa 14:13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
The king of Babylon is a type of satan, the king of the world or the coming antichrist beast. Lucifer is the devil.
I will sit also upon the mount of the congregation, in the sides of the north:
In the temple, which is what the beast will do, filled with the devil, in the end times.
2 Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2 Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, showing himself that he is God.
Isa 14:14 I will ascend above the heights of the clouds; I will be like the most High.
This was the fall of Lucifer, exalting himself as God.
Isa 14:15 Yet thou shalt be brought down to hell, to the sides of the pit.
Isa 14:16 They that see thee shall narrowly look upon thee, and consider thee, saying, Is this the man that made the earth to tremble, that did shake kingdoms;
Satan was not a man, but the false christ was a man.
Isa 14:17 That made the world as a wilderness, and destroyed the cities thereof; that opened not the house of his prisoners?
When the king of literal Babylon fell, his weakness was exposed and others were amazed that he once had so much power, and so many feared him. The same will happen when the king of spiritual Babylon falls. People will see him for what he really is and be amazed at how much power he actually had.(Guzik)
These supernatural evil men were given demonic power.
Eph 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
