It is becoming more apparent that much of the bible has indeed been manipulated by transcribers through the years. There is much info on the net concerning those things.
Have you ever looked at the first print of the king james ? It reads like a shakespearian play or something , we know the ancient jews did not use that type of language so to say it's an accurate translation would be far from the truth. People just seem to like the way psalms 23 was tampered with especially for some reason so they use it allot at funerals .At least king james left the name jehovah in at four different spots tho.
