The events of these weeks begin with the issuance of the decree by the Persian King Artaxerxes, by which the Jews were commanded to rebuild the city of Jerusalem. Upon the completion of sixty-two weeks, Christ Jesus, peace be upon him, will cease his work of prophecy in the land. He is, peace be upon him, the High Priest of the High Priests in the chain of Israel's prophets after Moses, peace be upon him, and he is also their last prophet, through whom prophecy in Israel was sealed. The King said to Daniel: "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 troublesome 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. And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate." (Daniel 9:25-27).

This is what actually happened, as the decree of the Persian King was issued in 443 BC. In 33 AD, Jesus, peace be upon him, was raised to heaven. The period between these two events is 476 years, which is equivalent to 483 solar years. The calendar adopted in the Holy Book by Jews and Christians is 69 weeks, where a week equals 7 years, as we said before.

However, the King did not mention the details of the last seventy weeks to Daniel. The reason for this is that the events of this last week will take place before the descent of Christ Jesus, peace be upon him, at the end of time, meaning its events will occur in the seven years preceding his descent.

(The monk Matta El Meskeen said in his book "Prophecy and Prophets in the Old Testament," p. 243, about this week: "A final week, which scholars call Daniel's week, although it is far from its time, it has not yet been completed, and it will have great importance in the future.")
