The septuagint (also known as the lxx) is a translation of the hebrew bible into the greek language The name septuagint comes from the latin word for “seventy.” the tradition is that 70 (or 72) jewish scholars were the translators behind the septuagint. The septuagint, also called the lxx (or seventy), was also the version of the bible that the early christians primarily relied on — both in greek and then in latin translation — until protestants returned to the masoretic hebrew in the 16 th century. Note that the so called 'sixth' chapter of baruch in the septuagint is published separately as letter of jeremiah
