The discovery of the Dead Sea Scrolls of the Essenes, a conservative religious sect that lived ~200 BC, has shed new light on Hebrew Scripture. Every book of the Old Testament was found in the Dead Sea Scrolls except for the Book of Esther. It is important to note that the Dead Sea Scrolls included 3 books written in Hebrew which had been considered part of the Apocrypha - Tobias (or Tobit), Sirach, and the Letter of Jeremiah, as well as Psalm 151 of David. Also discovered were two books of the pseudepigrapha, the Books of Enoch and Jubilees, both of which are also found in the Old Testament of the Eastern Orthodox Church of Ethiopia.
