This site has a video on the King James Verses NIV & NASB and no doubt there are differences which are made also because the King James is non copyrighted and to make a copyrighted versions it has to be different in some form so it would not be a copy of the King James. But it is also easy to make a more better translation from the original languages used as the King James picked out the word they wanted to use in translation. The King James is better then these others in my opinion and many others feel that way too. Here's a video on it.
This is the the remnant of God site.

This site compares the King James with the NIV & NASB but not The Interlinear Bible Hebrew Greek English Coded with Strong's Concordances not the Jewish One Man Bible that Sid Roth promotes as a very good one on Christian T.V. which I find to be very good as well.
On the Same Remnant of God site that promotes the King James & had the video on that is also showing verse and word meanings from the King James that also through research on my own and with the Concordence changed my view on the Standard doctrine view of hell.

Is Hell For Eternity?

It shows all the verse's words used in other verse's and the Scripture could seem to contridict itself without deep study of the meaning of these words in contrast to other scripture that use them as well. Based on the language in english word translation the King James choose to use. Many standard King James bible based Christians and Ministries etc.. have changed their taught standard view on the subject by researching and studying it themselves. It was because of Christians who got to read and study the Bible themselves that left the standard this is the way we have always taught it thing. In reading the history of the Church we can see why the Church broke up and the martyrdom of history because of it. Based on that we all get to see for ourselves what it says and own a Bible today.

I think many of the issues of differences start with... "this is the way I interpert it this is the way I see it this is the spin I put on it this is the word meaning I choose now lets start from here." I had to back away from all of that to study & read both sides and look up the verses and the word meanings myself to see what it all says.. I see how people can say well look at these scriptures and the other side says well look at these scriptures then they end up talking at each other past each other and hit a brick wall. I had to step back from that start fresh and say O.K... Lets take a fresh look at it myself shutting out what others say about the subject and starting fresh. Thank God that the people own the Bible now in lew of how it use to be in the historical past where the Church owned the Bible and told us what it said and how to interpret it. This is where freedom starts the freedom to debate the freedom to believe the freedom to know and the freedom to search for oneself . That's why I believe it the way I see it of now and I believe it to be Biblical too. And yes I do believe there is a Hell & it's for reals! It's a Biblical Fact.
