Isaiah 14:12-15
"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! 13For thou has 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: 14I will ascend above the heights of the clouds; I will be like the most High. 15Yet thou shalt be brought down to hell, to the sides of the pit."
Your problem lies with identifying Lucifer. Are these verses talking about a king on earth (who fell because of pride) or a Rebel?
