How are you fallen from heaven, O Lucifer, son of the morning! how are you cut down to the ground, who did weaken the nations!
All Commentaries on Isaiah 14:12 Go To Isaiah 14
Jerome
AD 420
Lucifer fell, Lucifer who used to rise at dawn; and he who was raised in a paradise of delight had the well-earned sentence passed upon him: “Though you exalt yourself as the eagle, and though you set your nest among the stars, thence will I bring you down, says the Lord.” For he had said in his heart, “I will exalt my throne above the stars of God,” and “I will be like the Most High.”
