Seventy weeks

a prophetic period mentioned in Dan. 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.
