What Role Did King James Play In The Bible?

He got a group of biblical scholars to work on a revised version of the bible. It became known as the King James Version-KJV. Also known as the Authorised Version.

If you meant, in terms of the instrument he played then the answer is a 'Harp'.

Regards,

King James was the one person instrumental in making the Bible accessible to all.  He had hundreds of scribes take the religious scrolls that were available and figure out which ones were the most ordained of God, and not just someone's biased opinion, or legend.  The scribes were to have this book available by a certain festival given by King James.  What we have now is the result.
