I found the link to Edward F. Hill's book while searching for informations my friend is looking for. Maybe this link will be a blessing to someone else too.

One question he had was "How do you know the text which KJB was based on is preserved by God?"
I haven't had time to read Edward Hill's book yet. But can anyone explain to me in simple terms how do we know the texts they were using to translate the KJB were preserved by God? Thanks for your help.
