This translation, often used in the Catholic Church, follows the original Hebrew, Aramaic, and Greek texts. For the Old Testament the "Masoretic Text" established in the 8-9th centuries AD by Jewish scholars, is used. Only when this presents insuperable difficulties have emendations or other versions, such as the ancient Greek translation begun in 200 BC at Alexandria, the "Septuagint" (LXX), been used.
