Sea Scrolls. Other source details, such as Codex Sinaiticus, are as described below: "Where the Old Testament translation supposes the received text—Hebrew, Aramaic, or Greek, as the case may be—ordinarily contained in the best-known editions, as the original or the oldest extant form, no additional remarks are necessary. Where the translators have departed from those received texts, e.g., by following the Septuagint rather than the Masoretic text, accepting a reading of what is judged to be a better textual tradition, as from a Qumran manuscript, or by emending a reading apparently corrupted in transmission, such changes are recorded in the revised edition of the Textual Notes on the New American Bible. Additional information on the textual tradition for some books may be found in the introduction to the book in the same Textual Notes. "In particular, important manuscripts from Cave 4 of Qumran, as well as the most useful recensions of the Septuagint, have been consulted in the preparation of 1 and 2 Samuel. Fragments of the lost Book of Tobit in Aramaic and in Hebrew, recovered from Cave 4 of Qumran, are in substantial agreement with the Sinaiticus Greek recension used for the translation of this book. The lost original Hebrew text of 1 Maccabees is replaced by its oldest extant form in Greek. Judith, 2 Maccabees, and parts of Esther are also translated from the Greek. The translation of The Wisdom of Ben Sira is based on the original Hebrew as far as it is preserved, with corrections from the ancient versions; otherwise, the Greek of the Septuagint is followed. In the Book of Baruch the basic text is the Greek of the Septuagint, with some readings derived from an underlying Hebrew form no longer extant. In the deuterocanonical sections of Daniel (3:24–90; 13:1–14:42), the basic text is the Greek text of so-called Theodotion, occasionally revised according to the Greek text of the Septuagint." Reasons for revision In a press statement, the USCCB cited three reasons for the necessity of revising the Old Testament. The new translation: Aims to utilize modern scholastic advances in biblical study and adapt to changes in linguistics in order to render a more accurate translation in contemporary English. Takes advantage of recently discovered ancient manuscripts like the Dead Sea Scrolls which provide better access to the historical textual tradition. Uses the best manuscript-translating traditions available in order to translate more literally and accurately
