Actually there were many errors in the first editions of the King James. Most all of them have been corrected through time. One obvious error, not made by other early English translations can be found in Matthew 23:24. The Greek text is “strain out” not “strain at.” Unfortunately both the modern Oxford and Cambridge editions (which have different readings) of the KJV still retain the same error.
