Definitions for "Septuagint"
A Greek version of the Old Testament; -- so called because it was believed to be the work of seventy (or rather of seventy-two) translators.
From the Latin for seventy ( septem-ginta [decimal suffix]), composed over decades in the 3rd and 2nd centuries BCE. This was the premier version used by early Greek-speaking Christians, and so became the basis of the Christian canon. The name "seventy" derives from a tradition that Ptolemy II (285–247 BCE) commissioned 70 or 72 elders to prepare the translation, a task they accomplished in a miraculous 72 days. Copies of the Greek scriptures were found among the Dead Sea Scrolls (e.g., 4QLXXLeviticus-a, 4QLXXNumbers, 4QLXXDeuteronomy, pap7QLXXExodus, XHevXII gr). Even more interesting are Hebrew manuscripts that vary from the received Masoretic Text in the same places that the Septuagint does, suggesting that the Septuagint variants were not created by the Greek translators but instead faithfully reflect a Hebrew Vorlage or antecedent textual tradition (4QJeremiah b, 4QJeremiah-d; cf. also 4QLeviticus-d, 4QDeuteronomy-q, 4QSamuel-a, 4QNumbers-b, and 4QExodus-b).
(Gr., "seventy.") Abbreviated LXX. Translation of the Hebrew Scriptures into Greek, starting in the third century B.C.E. and requiring over a century to complete. It was the Bible of early Christians. The name derives from a legend that seventy Jewish elders were commissioned separately to do the translation, and yet their finished translations agreed in every detail.
