Ok let's break this debate down.
Underlying point: Luke 4 is not found
word for word anywhere in Isaiah.
What are the possible reasons?
1) Jesus read from a passage in Isaiah that we have no record of.
2) The passage in Isaiah has been corrupted.
3) Jesus misquoted Isaiah.
4) Luke Misquoted Jesus reading Isaiah.
5) Luke misquoted Jesus while misquoting Isaiah.
6) Jesus corrected Isaiah with His own version.
7) Isaiah missed the boat when the Holy Spirit "moved".
8) They handed Jesus the wrong scroll.
9) He read from the Septuagent.
10) He read from another version that no longer exists.
11) He created new scripture that day.
12) When Jesus asked for the KJV, he was handed another MV instead.
OK, I know a couple is way out in left field, but I wanted to be "complete". Get it, the number 12!
Ok,Ok, Bad Joke.
But seriously, the fact is, what is in our KJV in Luke 4 is not in our KJV anywhere in Isaiah "word for word". And to believe that Jesus corrected Isaiah leads to the following outcomes.
1) Isaiah is wrong.
2) Jesus is wrong. (God Forbid!)
3) We have a Jesus version in Luke 4.
4) Luke is wrong about what Jesus read.
5) Luke is wrong about Jesus even reading.
Now, If any of the above people (Jesus, Isaiah, or Luke) is wrong, then we have a mistake in the inspired Bible.
But OTOH (on the other hand), if Jesus used any other version to read or quote from (LXX, another, or even Himself) then he used another version! Which means he either sinned because he used something different than the KJV, (or the KJVs underlying texts), or It is OK to use other versions. And since Jesus never sinned then It is OK to use other versions.
And as Precepts has already pointed out,
"...We may not say exactly word for word what the Lord has said, but the subject matter isn't to be altered or misleading in our report."
That is what we mean when we say, that even though other versions have different words, they mean the same thing!
somemore possibilities:?
1)Erasmus found Luke 4 in the vulgate.
2)Westcott and Hort slipped back in time and took out some of Luke 4.
What? Stop with the possibilities.
OK, Oh well, you get the Picture.
Jesus didn't use the KJV!!!
