Daniel 9:25 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, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
What does this verse involve? It involves 69 of the 70 weeks, right?
Right.
[ Prove that it involves anything outside of these 69 weeks, IOW, apply the same logic that you are applying to verse 27, that even though verse 27 pertains to the 70th week, you insist some of it isn't. That's not the pattern seen in verse 25, though.]
I only apply that logic because v27 demands it by saying the prince to come would destroy the city and the sanctuary. This occured 40 years after Messiah was declared after the 69 weeks to confirm the NC in the Final week.
The destruction and desolation has nothing to do with the accomplishments of Jesus atonement victory in the 70th week.
24 “Seventy weeks have been decreed for your people and your holy city,
to finish the transgression,
to make an end of sin,
to make atonement for iniquity,
to bring in everlasting righteousness,
to seal up vision and prophecy
and to anoint the most holy place.
Heb 9
11 But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation; 12 and not through the blood of goats and calves, but through His own blood,
He entered the holy place once for all, having obtained eternal redemption. 13 For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh, 14 how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?
15 For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.
but now once at the consummation of the ages He has been manifested to put away sin by the sacrifice of Himself. 27 And inasmuch as it is appointed for men to die once and after this comes judgment, 28 so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him.
