How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! 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: I will ascend above the heights of the clouds; I will be like the most High. Yet thou shalt be brought down to hell, to the sides of the pit. 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; That made the world as a wilderness, and destroyed the cities thereof; that opened not the house of his prisoners?
As the song continues, the theme expands from the fall of the king of Babylon to the fall of the one who energized him, Satan, Lucifer, himself. Because Lucifer, the son of the morning, proudly asserted his will above the will of God, he was cast out of heaven. Eventually, he will be consigned to Sheol, an object of astonishment. Those in Sheol will marvel that one who exercised such power has been brought so low.
