The Septuagint (from the Latin septuaginta, “seventy”) is a translation of the Hebrew Bible and some related texts into Koine Greek. As the primary Greek translation of the Old Testament, it is also called the Greek Old Testament. This translation is quoted a number of times in the New Testament, particularly in Pauline epistles, and also by the Apostolic Fathers and later Greek Church Fathers.
