Diction, Syntax, and Voice

The Bible, as many other works of literature -- literature, I say, though the Bible is God's Word -- is colored by voice, and not just one voice, but 66 different voices, one for each book contained in it. This is especially evident in the KJV, the most polished and literary version of all. My question pertains to the changes in a rough draft that must be made to create such a voice. I don't know if the authors of the Bible ever needed to compose any rough drafts, but certainly the authors of all other works of literature did. Can the diction and syntax of an ordinary sentence be changed to create voice? Or is it the message itself that just happens to sound like that? I have found it very difficult to change the wording of the Bible so that it does not sound like the Bible.

Now, although I have wanted in the past to emulate the voices of scripture, I am trying to leave it alone, seeing it is the Word of God, and should remain unique -- not that anyone could ever duplicate it. But for the purpose of writing in a voice that I choose, I must know what elements of language to manipulate and how to manipulate them. Is it simply by changing the order of the words or the sentence structure that I can achieve voice? Does the diction have something to do with it?

I have had success with this in the past at times when I had increased verbal ability, although I do not think that the voice I achieved was very good. But now I seem to have trouble editing. I can write in this very common voice right now, but when editing a draft for effect, I can't seem to get it to sound like much of anything. It is for this reason that I present these questions. I must grasp some basic knowledge of writing.

One last question I must ask is this: When did the Bible begin to sound like our best English bibles (the KJV for instance)? Was it when it was written in the original languages, or when it was translated? Where did this sound come from, if the Lord did not inspire it, that is, if it was not present in the original languages?
