Lucifer

There isn't anyone named Lucifer, that entity is only known as bringer of light, shining one, morning star, and the king of Babylon. The Latin word lucifer was left untranslated in Isaiah.

Isaiah 14 is Israel's taunt against Babylon and it's King.

In Job 11:17, lucifer is translated as morning.

In 2 Peter 1:19, the same word is translated as morning star

There is a main adversary, usually referred to as dragon or serpent. And many satans/adversaries and stars (aka lucifers). Revelation 12:4 The DRAGON sweeps a third.

Star fallen from heaven to earth gets the key to the bottomless pit, opens the pit out comes locusts - only the people who do not have the seal of God on their foreheads are harmed. This star was brought out by the fifth angel. Revelation 9:1

Ezekiel 31:16 Assyria? In the day when he ??Assyria?? went down to Sheol ... when I cast him down to Sheol with those who descend into the Pit //children of men// ... They also went down with him to Sheol - Egypt and Assyria were are potrayed as being in Eden? Also Ezekiel 26:20

Daniel 8:10-11 the small horn hurled some of the hosts and the stars down to the earth and trampled them. It set itself up as the Prince of the host. Took away the daily offering and the place of his sancturay was thrown down.

Matthew 25:29 - after the trouble of those days the sun will be darkend and the moon will not give it’s lights and the stars will fall from heaven and the powers of the heavens will shaken. Mark 13:25

Luke 10:18 Jesus said he watched Satan fall like lightening from heaven.

NOTES

Lucifer is a word that was not translated for effect, but it at the very least refers to a human king - and may also allude to the spiritual Prince placed over Babylon.

Isaiah 14 tracing all the entities referenced is tough unless you use a highlighter.
