The Septuagint 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 in the New Testament, particularly by Paul, and also by the Greek Church Fathers. The title and its Roman numeral acronym LXX refer to legendary seventy Jewish scholars who solely translated the Five Books Of Moses as early as the late 2nd century BC.
This English translation by Sir Lancelot C. L. Brenton, published in 1851, is considered a long-time standard. For most of the years since its publication it has been the only one readily available, and has continually been in print. It is based primarily upon the Codex Vaticanus and contains the Greek and English texts in parallel columns.
The Brenton translation of the Septuagint is in the public domain.
