Your grip on the KJV is admirable but it will come with it's own set of problems . There is no "Lucifer " but there is a morning star , but oh well . We see it differently , have a good day !
Nah, it ain't got nothing to do with the KJV Bible nor any other English Bible translation from the Hebrew.
I feel led by The Holy Spirit to say this to you, and for the benefit of other brethren, just in case.
IF... you do not understand why... that idea of 'morning star' (Hebrew heylel) was used by our Heavenly Father about the devil in that Isaiah 14:12 Scripture, then that means you... are the one with the "set of problems". Why do I say this?
Because if you do not understand that God was pointing directly to Lucifer himself with the following words, then it means you deceive yourself about just what subject God is revealing there...
Isa 14:12-15
12 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!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit.
KJV
That in 'red' above is God repeating what LUCIFER himself has claimed in coveting God's Throne!
When... did Lucifer first make that false claim??? Back when Lucifer originally rebelled against God in coveting God's Throne in wanting to be GOD, back in the 'old world' when he fell. (Do you really think Nebuchadnezzar was the first to claim to be God?)
The particular danger you might... be in, by not understand this:
Lucifer, the devil, or Satan if you prefer, is COMING AGAIN TO PLAY GOD, on earth, with the power to work great signs and wonders that will deceive the whole world, except Christ's very elect. That is what the coming "great tribulation" is going to be about. Many will bow to the devil playing Christ at the end of this world, and they won't even suspect it, that's how fooled the majority of the world will be. That is the "strong delusion" that Apostle Paul was warning about in 2 Thess.2.
So if the Bible student cannot figure out that God is pointing directly to the devil in that Isaiah 14:12 verse, then it shows they do not understand what the devil did to rebel originally in the first place, nor will they be prepared to make a stand for Christ at the end of this world when the devil is allowed to come to earth and do that again.
