The Sum of Awe,
There have been very few actual changes to the Bible. By comparing Bible translations, any errors that have found there way into God's word can be eisly found and corrected. About the only errors that no one can be sure of is the spelling of names. One reason is that many people in ancient times had several different names, a different name for each of the languages that he spoke, at the time. The fact is, God Himself promised that He would not let His word become adulterated, Ps 12:6,7. It is God's purpose to judge the world of mankind by what is stated in His word, Rom 3:5,6, Acts 17:29-31. Any error in the Bible has nothing to do with the message that God has had recorded for mankind. The truth of God's word can be found in any Bible, it just takes more time in some, because you must look of references to some scriptures.
Over the years, as languages change, there must be an updating of the word into language that we understand, the actual meaning in todays words.
Also, when a translator translates from one language to another there are some words that do no have exact synonyms in the other language.
Think about this; Probably the worse thing that Bible translators have done is to remove God's Personal, Proper name from His own Book. Because of this, many people do not even know that God has a personal name.
In the original, inspired Bible books, God's name JEHOVAH, was recorded over 7,000 times. The old KJV Bible had God's name in it 4 times, Ex 6:3, Ps 83:18, Isa 12:2,26:4. The New KJV translators have removed God's name completely.
What do you think God will do to those people who have removed His name from His own Bible??? Rev 22:18. Personally, I would not want to be in their shoes when they stand before the throne of the Almighty God, JEHOVAH, Rom 14:10.
