You’re right that the King James Version of the Bible sounds much better than more recent versions when read aloud. It is not Old English, though. Google “old english example” to see some, if you’d like. I tried to post a copy of the Lord’s Prayer translated to Old English, but FR’s ongoing punctuation difficulties made it unintelligible.
Yeah; technically KJV isn’t Old English. Learned that when a seminary student. I used that term ‘cause it’s kind-a sort-a in that vein. It is so beautiful.
