Isaiah 14:12 (King James Version) How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! The use of Lucifer as an epithet for Satan comes from a passage in Isiah 14:12, which actually refers to Nebuchadnezzar, the King of Babylon, who was compared to the morning star; early Christian writers took this passage to be alluding to the fall of the archangel who was hurled from heaven because of his wickedness. http://www.randomhouse.com/wotd/index.pperl?date=19970624 Lucifer is a Latin word made up of two words, lux (light; genitive lucis) and ferre (to bear, to bring), meaning light-bearer.

As Alatea has stated, “Lucifer as an epithet for Satan” “actually refers to Nebuchadnezzar”. The expression “shining one,” or “Lucifer,” is found in what Isaiah prophetically commanded the Israelites to pronounce as a “proverbial saying against the king of Babylon.” (Isaiah 14:4) The description “shining one” is given to a man and not to a spirit creature is further seen by the statement: “Down to Sheol you will be brought.” (Isaiah 14:15) Sheol is the common grave of mankind—not a place occupied by Satan the Devil (I’m sure some may debate this). Regardless, those seeing Lucifer brought into this condition ask: “Is this the man that was agitating the earth?” (Isaiah 14:16) Clearly, “Lucifer” refers to a human, not to a spirit creature. The Hebrew word translated “Lucifer” means “shining one.” The Septuagint uses the Greek word that means “bringer of dawn.” Hence, some translations render the original Hebrew “morning star” or “Daystar.” But Jerome’s Latin Vulgate uses “Lucifer” (light bearer), and this accounts for the appearance of that term in various versions of the Bible. --- Regarding Revelation 12:7: I've looked at 20 different bible translations and none of them use Lucifer in that scripture. Rev 12:7 refers to the battle Christ and his army has against Satan (the Dragon) and his army. If there is a reference to show that Satan is Lucifer from this scripture then it escapes many, many bible scholars. As for Isaiah 14:12 it needs to be read in context with the surrounding scriptures. Did you not notice Isaiah 14 verse 4 and 16? Just a comment: We need to be very careful when examining the scriptures because if I did the same thing you do then I could even prove that there is no God from the bible by quoting one scripture too: Psalms 14:1 says "there is no God." But if I quote in context it says: The fool says in his heart, "There is no God." They are corrupt, their deeds are vile; there is no one who does good.

Yes, he was a cheribum over the ark of the covenant in the first earth age.

Originally not, but later in Modern and late Medieval Christian thought: "Lucifer is a Latin word meaning "light bearer" (from lux, lucis, "light", and ferre, "to bear, bring"), a Roman astrological term for the "Morning Star" the planet Venus. The word Lucifer was the translation of the Septuagint Greek heosphoros, ("dawn-bearer"; cf. Greek phosphoros, "light-bearer"; itself the translation of the Hebrew Helel ben Shahar, Son of Dawn), used by Jerome in the Vulgate, having mythologically the same meaning as Prometheus who brought fire to humanity. Passage 14:12 from the Book of Isaiah (see below) referred to one of the popular honorific titles of a Babylonian king; however, later interpretations of the text, and the influence of embellishments in works such as Dante's Inferno and Milton's Paradise Lost, led to the common interpretation in Christian belief that Lucifer was a poetic appellation of Satan. Modern and late Medieval Christian thought derived from this interpretation the idea that Lucifer is a fallen angel who is Satan, the embodiment of evil and an enemy of God. In Christian literature and legend, Lucifer is generally considered to have been a prominent archangel in heaven, although Book of Ezekiel 28:14 says: "You were the anointed cherub who covers, And I placed you there." In the fully-developed theme of "The War of Heaven", Lucifer had been motivated by pride to lead a revolution against God. When the rebellion failed, Lucifer was cast out of heaven, along with a third of the heavenly host, and came to reside in the world."
