He led the angels in a rebellion.There was a war in Heaven. Lucifer along with a third of the angels were cast out of Heaven. He is described as the originator and chief practitioner of sin, that wicked one, a thief, a destroyer, a deceiver, murderer, and liar. 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:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit. 8 And prevailed not; neither was their place found any more in heaven.
9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
