I have done some real reading about the awful KJV, the worst translation available in English today. More importantly, I have real experience with the KJV. Those who read KJV tend to be IDOLATORS, which kept me from reading the Bible for decades!
"Thee" and "thou" are not nitpicking, stupid and irrelevant but proof the KJV is archaic. It might be true that the best translation of the Bible is in German but I don't speak German. And I don't speak Middle English either. My friends and I don't "whithersoever thou goest" too often.
Joshua 1:9
King James Version
9 Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest.
