What is a Commentary?

A Bible commentary is a book that tells readers what the Bible means.  Commentaries do have some bias simply because they are written by humans. Commentaries are useful to make passages haven’t been severely misunderstood or missed an important point.  Commentaries should only be read after you have have studied a passage for yourself.
