Isaiah 14:12

From heaven; from the height of thy glory and royal majesty. As kings are sometimes called gods in Scripture, so their palaces and thrones may be fitly called their heavens. O Lucifer; which properly is a bright and eminent star, which ushers in the sun and the morning; but is here metaphorically taken for the high and mighty king of Babylon. And it is a very usual thing, both in prophetical and in profane writers, to describe the princes and potentates of the world under the title of the sun or stars of heaven. Some understand this place of the devil; to whom indeed it may be mystically applied; but as he is never called by this name in Scripture, so it cannot be literally meant of him, but of the king of Babylon, as is undeniably evident from the whole context, which certainly speaks of one and the same person, and describes him as plainly as words can do it. Son of the morning: the title of son is given in Scripture not only to a person or thing begotten or produced by another, but also in general to any thing which is any way related to another; in which sense we read of a son of stripes, Deuteronomy 25:2, the son of a night, Jonah 4:10, a son of perdition, 1 Thessalonians 17:12, and, which is more agreeable to the present case, the sons of Arcturus, Job 38:32.
