"Seventy weeks [490 days, prophetic time, or 490 literal years] are determined [cut off, as the word means] upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the Most Holy." Verse 24.
This 490-year period "cut off" was to cover the history of the people of Jerusalem until that city had filled out the measure of its transgression. The only prophetic period from which this 490 years can properly be said to be "cut off" is, assuredly, the longer period of 2300 years, which stretches far onward to "the time of the end." The 490 years and the 2300 years, then, must begin at the same time.
It was the time period that the angel Gabriel was yet to explain; and he begins the explanation by showing that the first 490 years of it would reach to the days of the Messiah. Then he gives the event that marks the beginning of the 490 years, which event must necessarily mark the beginning of the 2300 years as well.
This is what he was commissioned to make Daniel "understand" when first the vision of the 2300 years was given. Now he tells him to "understand" it:
"Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. And after threescore and two weeks shall Messiah be cut off, but not for Himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined." Dan. 9:25, 26.
The date of the going forth of the commandment to restore and rebuild Jerusalem is the date, therefore, from which the great prophetic measuring line runs; the first 490 years of it to reach to the time and work of the Messiah, at the first advent, the full 2300 years running on to mark the time when the judgment hour in heaven opens. Once the starting-point is fixed, all the events of the long period must follow exactly as scheduled in the time-table of divine prophecy.
Date of the Commencement to Restore Jerusalem
There were several commands issued concerning the restoration of Jerusalem after the Babylonish captivity. Cyrus, and Darius, and Artaxerxes Longimanus each issued such a decree. Which one answers to the language of the prophecy as "the commandment to restore and to build Jerusalem"?
