The books in the apocrypha are of Jewish origin but are not considered authoritative by Jewish readers.  Many Christians in the centuries after Christ valued these books and came to consider them authoritative for Christian faith and life.  During the Reformation in the sixteenth century, Protestants challenged the authority of the apocryphal books and eventually ceased including them in their Bibles.

The books of the Old Testament Apocrypha include...

1. 1 Esdras
   
2. 2 Esdras
   
3. Tobit
   
4. Judith
   
5. Wisdom of Solomon
   
6. Ecclesiasticus or Sirach
   
7. Baruch
