SEV'ENTY, noun The Septuagint or seventy translators of the Old Testament into the Greek language.

A prophetic period mentioned in Daniel 9:24, and usually interpreted on the "year-day" theory, i.e., reckoning each day for a year. This period will thus represent 490 years. This is regarded as the period which would elapse till the time of the coming of the Messiah, dating "from the going forth of the commandment to restore and rebuild Jerusalem" i.e., from the close of the Captivity.
