Daniel 9:24-25

24“Seventy weeks [of years, or 490 years] have been decreed for your people and for your holy city (Jerusalem), to finish the transgression, to make an end of sins, to make atonement (reconciliation) for wickedness, to bring in everlasting righteousness (right-standing with God), to seal up vision and prophecy and prophet, and to anoint the Most Holy Place.

25So you are to know and understand that from the issuance of the command to restore and rebuild Jerusalem until [the coming of] the Messiah (the Anointed One), the Prince, there will be seven weeks [of years] and sixty-two weeks [of years]; it will be built again, with [a city] plaza and moat, even in times of trouble.
