End Times Commentary 3:
24 "Seventy weeks
[70 weeks] are determined 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.
25 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
[7 weeks], and threescore and two weeks
[62 weeks]: the street shall be built again, and the wall, even in troublous times.
26 And after threescore and two weeks
[62 weeks] shall Messiah be cut off, but not for himself
[The Messiah is Jesus who is the Lamb of God who takes away the sins of the entire world]: and the people of the prince
[the people of the prince of the power of the air, i.e. the devil - see: Ephesians 2:2] that shall come shall destroy the city and the sanctuary
[i.e. the Romans destroyed the Jewish temple in 70AD]; and the end thereof
shall be with a flood, and unto the end of the war desolations are determined.
27 And he
[The "he" is the "prince" of the people mentioned in verse 26] shall confirm the covenant with many for one week
[make a treaty with the Jews and others in the final 7 years]: and in the midst of the week he shall cause the sacrifice and the oblation to cease
[this prince will stop the Jewish sacrifices in the temple], 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 9:24-27).
After 7 weeks (49 days /49 years) = Temple Rebuilt (verse 25).
+ (Plus)
After 62 weeks = (a) Christ dying for our sins (b) 70AD Temple destruction.
(Verse 26).
(Gap of time or Age of Grace: The War (verse 26), or Spiritual Time of Battle for the Cause of Christ in Spreading the Gospel)
+ (Plus)
The last 1 week (7 days/7 years) = Tribulation period (verse 27).
7 + 62 + 1 = 70 Weeks.
This passage sets the backdrop or framework for Daniels 70 Week Prophecy (verse 24).
Side Note 1:
If you were to carefully look at the text, it states that there are things that happen in the gap like a.... "war" until the end. Also, Christ dies, and the temple is destroyed also within the gap of time that is not accounted for within the 70 weeks, as well. The text is actually saying that things are happening within the gap of the 69th week, and the 70th week.
Side Note 2:
The texts in brackets in blue and red in the Daniel 9 passage is my personal commentary on the text.
