The Septuagint (pronounced sep-TOO-uh-jint) is a Greek translation of the Jewish Scriptures, completed sometime between 300 to 200 BC.
The word Septuagint (abbreviated LXX) means "seventy" in Latin, and refers to the 70 (or more accurately, 72) Jewish scholars who supposedly worked on the translation. Many ancient legends exist as to the book's origin, but modern Bible scholars have determined the text was produced in Alexandria, Egypt and finished during the reign of Ptolemy Philadelphus.
