Who wrote magna est veritas et praevalebit?
A verse in the Book of Edras (Ezra) in the Latin Vulgate Bible,
which was in common use before the English language King James
Bible, reads "Magna est veritas et praevalet" which means "Great is
the truth and it prevails". The version in the question is a common
misrepresentation which actually means "The truth is great and
shall prevail"
