What is the 7th book of the Old Testament of the Bible?
The seventh book of the Old Testament (and Hebrew Scriptures) is
the book of Judges. Genesis, Exodus, Leviticus, Numbers,
Deuteronomy and Joshua all proceed Judges. In the categorizing of
the Hebrew Scriptures in Judaism, the book of Judges is part of the
Nevi'im, "The Prophets".
Christian categorizing of the Old Testament has no such official
categorizing.
