The Bible was written by fisherman, shepherds, and for the most part, very unlearned people, in poor Hebrew and poor Greek.
It was not written by a high and lofty king and his chief theologians and scribes for the use and furtherance of the Church of England. It was not written to have the sound of a classical Elizibethian-style English.
Though I do think that the KJV is a wonderful version, it is only a version, not the version.
I have ALWAYS wondered about this, what Bible do KJVOs want for non-English speaking people to read, or should they learn English?
