I don't mean to confrontational, but one of the reasons maybe that they didn't know the old languages as well as they do today. In the original King James there was an opening letter basically saying that they didn't know it all and we did our best. From what I have read it wasn't until the late 1800's that they made great strides in figuring out the old Hebrew and the old Greek. We benefit directly from that with Dr. Strong's and Dr. Bullinger's works.
I perceived no confrontation. I didn’t know why only the King James uses charity. As far as additional information and the help of Strong’s etc I agree. I also believe that is by God’s design knowing we would need additional support and information in these last days.
