Deuteronomy

Origin

From the name which the book bears in the Septuagint (Ancient Greek Δευτερονόμιον (Deuteronómion), from δεύτερος (deúteros, “second”) + νόμος (nómos, “law”) + -ιον (-ion), and in the Vulgate Latin Deuteronomium). This is based upon the erroneous Septuagint rendering of משנה התורה הזאת (mishneh ha-torah ha-zot) (17:18), which grammatically can mean only "a repetition [that is, a copy] of this law," but which is rendered by the Septuagint τὸ Δευτερονόμιον τοῦτο (tò Deuteronómion toûto), as though the expression meant "this repetition of the law."
