John Wesley on Isaiah 14:12

Fallen - From the height of thy glory. Lucifer - Which properly is a bright star, that ushers in the morning; but is here metaphorically taken for the mighty king of Babylon. Son - The title of son is given in scripture not only to a person or thing begotten or produced by another, but also to any thing which is related, to it, in which sense we read of the son of a night, Jonah 4:10, a son of perdition, John 17:12, and, which is more agreeable, to the present case, the sons of Arcturus, Job 38:32.
