You can say that you didn't understand that the 70th week has not begun yet.
Why would I say that? Why would anybody say that?
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.
