the Dead Sea Scrolls render the King James Bible obsolete?
No, they support it.
The Dead Sea Scrolls which were found by an Arab shepherd boy in 1947 in
the Qumran caves near Jericho, Israel have no ill effect on the Bible.
Their text actually agrees with the King James Bible.
This fact makes them unattractive to scholars desiring to overthrow the
perfect Bible. So, other than commenting on the irony of the way in which
they were found, they are largely ignored.
The translators of the King James Bible did not need the Dead Sea
Scrolls since they already had the Textus Receptus which they match.
