The point "to come" means what then?
Jesus was/is the Messiah who was to come.
Most of Christianity cannot see the 70 weeks as being broken into chunks of time. Because they all rely on a false teaching by the early church fathers, who sometimes were antagonistic against the Jews in general of their day.
Look at the history of the OT Canon. Even the adherents of Judaism did not all agree on Daniel as being part of the OT Canon.
Gabriel broke the week up in the text, not Bible teachers or theologians.
49 years happened. Then 434 years happened. That is how it was prophecied. Gabriel never said after 490 years. 49 plus 434 is only 483. So Gabriel said after 483 years Messiah would be cut off. The 70th week was never described at all. Not sure how one can change the text and declare a solid 490 years.
Instead of "breaks," I refer to them as milestones. A milestone is a noteworthy moment during a given time period. The time period remains uninterrupted by any of the milestones. God gave Israel 490 years to complete certain tasks, but they failed, leading to God's judgment against them.
Gabriel never stated: In 490 years Stephen would be stoned to death. That is human opinion placed on faulty interpretation and teachings.
I agree. Gabriel never explicitly mentioned Stephen or any other person who would mark the end of the 490 years. But, if you pardon my delay, I would like to explain more in my commentary below.
Since you claim not to see the Prince part, that would be the last 3.5 years. There was no Prince on earth who left at the stoning of Stephen. Nor were the promises of verse 24 enacted after the stoning of Stephen. Israel was not restored, all 12 tribes after the stoning of Stephen. The Day of the Lord did not start after the stoning of Stephen.
According to Gabriel, 490 years were allotted to Daniel's people to accomplish the following items: 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. Gabriel then predicts that Israel will fail to complete all these tasks in the allotted time, describing the final seven years.
Daniel 9:26 Then after the sixty-two weeks the Messiah will be cut off and have nothing, and the people of the prince who is to come will destroy the city and the sanctuary. And its end will come with a flood; even to the end there will be war; desolations are determined.
after the sixty-two weeks
Gabriel doesn't mean to indicate the "day" after the sixty-two weeks. He means to say, "the final week after the sixty-two weeks, which is the seventieth week. Sometime during week 70, the Messiah will be cut off and have nothing.
and have nothing
Presumably, Gabriel is speaking from the standpoint of the "Daniel 9:24 project." The Messiah would be cut off, i.e., put to death, and have nothing to offer the people in support of Israel's assigned task. (We know, from NT teaching that the blood of Christ would inaugurate the New Covenant.)
the prince who is to come
The Messiah is the prince who is to come, verse 25
the people of the prince
Some text witnesses have the following reading which makes more sense to me; “the city and the sanctuary will be destroyed with the coming prince.” "The coming prince was Jesus the Messiah. Not only will he be crucified, but also the city and the sanctuary will be destroyed. In other words, the cutting off of the Messiah will be the crime that leads to the destruction of the city and the sanctuary."
Daniel 9:27 And he will make a firm covenant with the many for one week, but in the middle of the week he will put a stop to sacrifice and grain offering; and on the wing of abominations will come one who makes desolate, even until a complete destruction, one that is decreed, is poured out on the one who makes desolate.”
a firm covenant
Rather than strengthening the Old Covenant, the purpose of the Messiah was to establish a firm covenant with God, which Jesus called "the New Covenant." Luke 22:20
for one week
Jesus' ministry lasted for about 3-1/2 years as he worked to establish the "firm covenant" (New Covenant). His crucifixion inaugurated the "firm covenant", which took place in the middle of week 70. After the allotted time of the "Daniel 9:24 Project" had expired, which I speculate was the Stoning of Stephen, the Lord called Saul, changing his name to "Paul", assigning him the role of Apostle to the Gentiles.
middle of the week
This refers to week 70, during which the Messiah was "cut off".
put a stop to sacrifice and grain offering
As Jesus said, his blood would inaugurate a New Covenant. Justification by faith in Jesus Christ replaces in a more profound and complete way, the sacrifice and grain offerings.
wing of abominations
The Hebrew term translated as "wing" carries the meaning of "extremity, edge, or boundary." In my understanding, Gabriel is referring to the "limit" of abominations, which was the ultimate transgression - the crucifixion of the Messiah - that resulted in the devastation and destruction of the city and the sanctuary.
one who makes desolate
Titus and the Roman army made Jerusalem desolate. He and his men came upon it like a flood.
