I think this presentation thoroughly refutes that. I’m not ‘KJV only’ because there are often occasions when I find something useful in one of the other translations (particularly the Eth Cepher, BSB, CJB, and ESV) and I regularly check the Hebrew, Aramaic, and Greek, but this guy is showing a great deal of irrefutable evidence that the KJV is at least one of the places where the Almighty has preserved His Word.
