Lucifer is not taken from the original Hebrew Helel, and the root halal, meaning shine, and represents the giving off of light by celestial bodies. As a proper name it is rendered “day-star” in ESV, HCSB, “star” in NASB.Lucifer is from the Latin Vulgate but interesting to note it is retained as a proper name in the AV (KJV). Originally meaning “shining, bright, clear.”So, in this case, the KJ did not translate from the original language.Ironically, the title “Day Star” is used of Jesus as “the bright morning star” (Revelation 22:16)Some believe it is actually a reference to the planet Venus.In context of Isaiah 14it is a reference to the King of Babylon.Some believe the passage has a double reference, one to the King of Babylon and then to Satan, thus recording Satan’s fall to earth. (Compare with Ezekiel where some teach reference to the King of Tyre also serves as a double reference, 28:12f).Lucifer/Satan becomes God’s archenemy and a symbol of rebellion.Satan’s fall (along with the angels) is a theme found OT Pseudepigrapha literature, which is captured in Revelation 12.Lucifer as Satan is a principle character in Dante’s Inferno (14th-century) as well as Milton’s Paradise Lost (1667)From the original Hebrew and the reference to the King of Babylon there is no evidence Satan was held in view and only becomes a double reference through tradition, perhaps heavily influenced by the Latin Bible The HammerMi kamocah ba'elim AdonaiWho is like you, Adonai, among the mighty?
