The mistakes that the King James translators may have made WERE NOT able to invalidate the word of God aka the King James Bible. When I'm witnessing or teaching or sharing the word of God I take my KJV and tell any soul.......THUS SAITH THE LORD OF HOSTS or I tell them .....IT IS WRITTEN and I take the word of God, the KJV and show them where it is written.<quoted text>Listen CAREFULLY. Did I not say that the original worsds from Gods mouth to the mind of mankind IS INFALLIBLE. but when man takes those words and try to translate them into another language it is very possible that mankind may make mistakes in the translation. The translators of the original King James Version was aware of this fact hence they placed those two letters into the 1611 KJV when they had finished translating it warning us to be careful when reading it because it is possible that due to them being humans and thus capable of making mistakes they may indeed have made a few in the translation/transliteration.
A wise man should be able to realize how honest those 1611 KJV translators were.
If you are a somewhat good Bible student and a mistake is there,by the power and revelation of the Holy Spirit you should be able to recognize when the translators were off track in their translating.
Just because the translators of the 1611 KJV stated that they may have made a few mistakes in translating the word of God into English,my faith is not so shaky that it cannot withstand that info. It is still the INFALLIBLE word of God. PEACE
