Sepʹtuagint

A Greek version of the Old Testament, so called because it was made, in round numbers, by seventy Jews; more correctly speaking, by seventy-two. Dr. Campbell disapproves of this derivation, and says it was so called because it was sanctioned and authorised by the Jewish Sanʹhedrim or great council, which consisted of seventy members besides the high priest. This derivation falls in better with the modern notion that the version was made at different times by different translators between B.C. 270 and 130. (Latin, septuaginta, seventy.)
