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
Augustine of Hippo
AD 430
For example, what is said in Isaiah, “How he is fallen from heaven, Lucifer, son of the morning!” and the other statements in that context that speak of the king of Babylon are of course to be understood of the devil. However, the statement that is made in the same place, “He that sent orders to all nations is crushed on the earth,” does not altogether fitly apply to the head himself.
