Have you ever tried to send an email or make a post when you are really really tired? Muddled words and wrong keystrokes, I cannot imagine how the translators got the task of laying out each individual letter by hand on a template for printing, no wait I correct that I can imagine, they had the Holy Spirit of God
But even at that it must have been a very arduous task and very very slow. Well at least they were not textual alterations but mere spelling and print errors.
In My Saviour's name, The LORD Jesus Christ.
