Bible Verses
Isaiah 14:12
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!
Latter-day Scriptures
Doctrine and Covenants 76:25-26
And this we saw also, and bear record, that an angel of God who was in authority in the presence of God, who rebelled against the Only Begotten Son whom the Father loved and who was in the bosom of the Father, was thrust down from the presence of God and the Son, And was called Perdition, for the heavens wept over him—he was Lucifer, a son of the morning.
