Septuagint

The Septuagint or LXX (from the Latin: septuāgintā literally "seventy"; sometimes called the Greek Old Testament) is the earliest extant Greek translation of the Hebrew scriptures from the original Hebrew.^[1] It is estimated that the first five books of the Old Testament, known as the Torah or Pentateuch, were translated in the mid-3rd century BCE and the remaining texts were translated in the 2nd century BCE.^[2] Considered the primary Greek translation of the Old Testament, it is quoted a number of times in the New Testament,^[3][4]particularly in the Pauline epistles,^[5] by the Apostolic Fathers, and later by the Greek Church Fathers.

Pre-Christian Jews Philo and Josephus considered the Septuagint on equal standing with the Hebrew text.^[14][52] Manuscripts of the Septuagint have been found among the Qumran Scrolls in the Dead Sea, and were thought to have been in use among Jews at the time.

The Early Christian Church used the Greek texts^[54] since Greek was a lingua franca of the Roman Empire at the time, and the language of the Greco-Roman Church (Aramaic was the language of Syriac Christianity).

In 2006 the International Organization for Septuagint and Cognate Studies (IOSCS) - a non-profit, learned society formed to promote international research in and study of the Septuagint and related texts ^[80] - declared February 8 "International Septuagint Day",^[81] a day to promote the discipline on campuses and in communities.^[81] The Organization also publishes the "Journal of Septuagint and Cognate Studies" (JSCS).
