The Septuagint (or LXX) is a translation of the Hebrew Bible and some related texts into Koine Greek. The title and its Roman numeral acronym LXX refer to the legendary seventy Jewish scholars who completed the translation as early as the late 2nd century BCE. As the primary Greek translation of the Old Testament, it is also called the Greek Old Testament. This translation is quoted in the New Testament, particularly in the Pauline epistles, and also by the Apostolic Fathers and later Greek Church Fathers. The traditional story is that Ptolemy II sponsored the translation for use by the many Alexandrian Jews who were not fluent in Hebrew but fluent in Koine Greek, which was the lingua franca of Alexandria, Egypt and the Eastern Mediterranean at the time.
