Daniel 9:24-25

24Seventy weeks are decreed upon thy people and upon thy holy city, to finish transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up vision and prophecy, and to anoint the most holy.

25Know therefore and discern, that from the going forth of the commandment to restore and to build Jerusalem unto the anointed one, the prince, shall be seven weeks: and threescore and two weeks, it shall be built again, with street and moat, even in troublous times.
