I only use the KJV in English and the Reina-Valera Antigua in Spanish.
The KJV is the only Bible that is not confusing. Remember it only takes one generation to make a word archaic. By the way...I believe the KJV is the only english language bible that does not have a copyright.
I suppose if you’re accustomed to it, then old English might not be too confusing. For myself, I can’t understand anything that’s going on in a Shakespeare play. There has been at least one occasion where I’ve taken the wrong interpretation from a KJV verse. I forgot the what exact verse was, though.
