It is important to understand that these 70 prophetic "weeks" do not happen all at once. Verse 25 shows that there will be a span of seven weeks, and then a second span of 62 weeks. Yet historically, the second block of time did not happen right after the first.
Obviously, 7 + 62 equals only 69 weeks, so one "week"—a span of seven years—still remains after verse 25. Verse 27 fills that in, showing that the Messiah's confirming of the covenant covers that final week: "Then [H]e shall confirm a covenant with many for one week."
Combining verses 26 and 27, we see that, in reality, the first half of that final week has also already taken place: It was the 3½ years during which Jesus Christ confirmed the New Covenant with the church, was cut off in the middle of the week, and brought an end to animal sacrifice and offering.
Perhaps this explains why, after Jesus' resurrection, the disciples ask Him if He would now restore the Kingdom to Israel (Acts 1:6). They were probably thinking, "Wow, what a week! And it's only half over!" Knowing the prophecies, they could see that many of the elements of Daniel 9:24 had been or were being fulfilled. Realizing that they had just made the New Covenant, they probably expected that the second half of the week was about to come to pass, too, and that the Israelites and the holy city would be the beneficiaries. No wonder they assumed it was time for the Kingdom to be restored! Instead, Jesus tells them that it was not for them to know the times or seasons—meaning the timing of when the prophecies would all be fulfilled—and instead they would receive the Holy Spirit and become witnesses of Him in Jerusalem, Judea, Samaria, and the ends of the earth (Acts 1:7-8).
We, too, should recognize that 3½ years are still left of His confirmation of the covenant—the same one we have made—and what remains of the prophecy relates to Jerusalem and the people of Israel, as Daniel 9:24 shows.
Thus, there will be a span of 3½ years at some point in the future, during which God will fully accomplish those six elements found in verse 24, and the beneficiaries will be physical Israelites. Though we will not know for sure until it happens, those 3½ years may correspond with the time of Jacob's Trouble, the reign of the Beast, the treading down of the holy city by Gentiles, and the persecution of the woman's offspring, as related in Revelation 12.
