It would require me to write a lengthy commentary of Daniel 9:27, Daniel 12:11-12, Revelation 11:3-10, Revelation 12:5-6, etc. but I am not planning to, so please study all of these verses first before read my position here.
My position is that the "he" of Daniel 9:27 is Jesus Christ Himself. He was cut off for His people, Israel. Not to be confused with national Israel, but Covenant Israel which make up of all of His chosen Elects from Old and New Testament. He has confirmed a covenant with many (not everyone on earth) for one week. So after the Cross, the church represents God's kingdom under this new covenant which spans from the Cross to the Second Coming which is the Consummation of the week. This is known as New Covenant Week.
You may wonder if Jesus Christ was the one who has confirmed a covenant, then the verse 27 shows that he also is the one who will have caused the sacrifice and the obligation to cease. What sacrifice is this? Didn't you realize that Jesus Christ is our high priest fulfilled Daniel 9:24 "to make reconciliation for iniquity?"
Hebrews 2:17 KJV
[17] Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.
We now know that Jesus Christ is our high priest bring sacrifice and oblation to God on our behalf. But Daniel 9:27 tells us that in the midst of the week, he (Jesus Christ) shall cause the sacrifice and oblation to cease! What is this talking about?
We need to go to Scripture to find out.
When we look at the one-week wilderness journey, we find that it is divided into two segments which are SPIRITUALLY a half week or half a week of years. God uses the term, "time, times and a half." I believe to illustrate this spiritual length of time. To signify that these are not literal periods of time. For example, it is a length of time which is not disclosed (for that would mean we would know when the consummation is, and no man knows the day and hour of the Lord's return, selah!) It is a whole New Covenant period, with specific time signposts only known to God. This time period is to represent a period where God's church (woman) went into the wilderness (world) where she is fed away with Gospel "FROM" the face of the serpent:
Revelation 12:14 KJV
[14] And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
This is the FIRST HALF of the week. Christ comes out of Israel (woman), and Israel is delivered of this man Child and she goes into the wilderness as CHURCH where she was Nourished/Fed for time, times, and a half (1,260 days). The same period that the Two Witnesses were to prophesy for 1,260 days (Revelation 11). It is a time of salvation as long as Gospel is fed through the Church!
Now, why does it says the woman is nourished for times, and a half, and not the full week of wilderness journey? Think about it. Because at the end of this "time, times, and a half" the sacrifice and offering for salvation
ceases! Why?
First, Christ has finished sealing all of His people through the Church. Second, it is now a time of spiritual famine within the woman, BECAUSE she is no longer fed away from the face of the serpent. In other words, when the testimony of the Two Witnesses for salvation is FINISHED, the beast will come out of bottomless pit and will overcome them and kill them (silence their testimony - not physically killed). This is WHEN Christ has caused the sacrifice and obligation needed for salvation to end and to loosen Beast from the bottomless pit and use him to overrun the unfaithful church and gave her into his hand for time, times and a half which is the second part of the week:
Daniel 7:25 KJV
[25] And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
This is the Great Tribulation period FOR THE SAINTS in the church! It is because the power of the Holy People has been scattered. Daniel wrote:
Daniel 12:7 KJV
[7] And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.
This is as we read in Revelation11 of the two candlesticks/Witnesses/prophets/olive trees bring killed, symbolically! God is painting the picture that when the testimony of Two Witnesses for SALVATION is finished because God has finished sealing all of His people, Israel through the testimony, the church is killed (silence) where the truth is no longer found. That is the language of sacrifice and offering (or the gift) ceasing. The churches testimony is finished because all Israel who is to be saved, has been saved. Because of the overspreading of the abomination that STANDS IN THE TEMPLE OF GOD (Church), they shall make the temple spiritually desolate! This is when the rise of false prophets and Christs taking sit (rules) in the church where Satans actually rules through them, bringing lying signs and wonders to unfaithful church. God sees them as the army of Gog and Magog because he is bringing them against His unfaithful Israel as a judgment. Even until the consummation. Till the end come, and judgment is poured out upon those who make it desolate. The church will remain desolate UNTIL the end when Christ returns.
That is the Biblical interpretation of the 70 weeks of Daniel Chapter Nine. The overview is that the 70 weeks go from the command to build again the City, to the Jubilee year, to the coming of Messiah the Prince of Israel, and after this 62 weeks, is Messiah cut off, and at the same time confirms or strengthens a New Covenant by His work on the cross, for one week. During this week, after the faithful testimony of the Two Witnesses has been fulfilled, the abomination stands in the holy place, and sacrifice and the gift cease when the army of false prophets and christs attacks the church. Therefore, there is
no more Salvation left in these churches and
the power of the Holy People is scattered. This will be the period of the spiritual famine of
hearing the Word of God so that there is
no free gift or sacrifice in the Temple. And this abomination shall leave the Temple desolate. And if these days of great tribulation and trouble weren't shortened, there would be no flesh on earth left to be Saved (as sacrifice and offering has ceased). But for the Chosen of God's sake, the days are shortened, that there will be a rapture! And that is at the end or the consummation.
