Septuagint

In early Christianity the Septuagint was universally used among Greek speakers, while Aramaic Targums were used in the Syriac Church. To this day the Eastern Orthodox Church uses the Septuagint, in an untranslated form. Some scripture of ancient origin is found in the Septuagint but are not in the Hebrew. These include additions to Daniel and Esther. For more information regarding these books, see the articles Biblical apocrypha, Biblical canon, Books of the Bible, and Deuterocanonical books.
Some books that are set apart in the Hebrew text are grouped together. For example the Books of Samuel and the Books of Kings are in the Septuagint one book in four parts called "Of Reigns" (Βασιλειῶν). Scholars believe that this is the original arrangement before the book was divided for readability. In the Septuagint, the Books of Chronicles supplement Reigns and are called Paraleipoménon (Παραλειπομένων—things left out). The Septuagint organizes the minor prophets as twelve parts of one Book of Twelve.
All the books of western canons of the Old Testament are found in the Septuagint, although the order does not always coincide with the modern ordering of the books. The Septuagint order for the Old Testament is evident in the earliest Christian Bibles (5th century). The New Testament makes a number of allusions to and may quote the additional books (as Orthodox Christians aver). The books are Tobit, Judith, Wisdom of Solomon, Wisdom of Jesus Seirach, Baruch, Epistle of Jeremy (sometimes considered part of Baruch), additions to Daniel (The Prayer of Azarias, the Song of the Three Children, Sosanna and Bel and the Dragon), additions to Esther, 1 Maccabees, 2 Maccabees, 3 Maccabees, 4 Maccabees, 1 Esdras, Odes, including the Prayer of Manasses,
The canonical Christian Bible was formally established by Bishop Cyril of Jerusalem in 350 and confirmed by the Council of Laodicea in 363, and later established by Athanasius of Alexandria in 367. The Council of Laodicea restricted readings in church to only the canonical books of the Old and New Testaments. The books listed were the 22 books of the Hebrew Bible plus the Book of Baruch and the Epistle of Jeremy, together with the New Testament containing 26 books, omitting the Book of Revelation.
