The "midst of the week," I believe, is the time he himself arrives. He is the fake pretending to be Jesus. Because of his deception, when the world will believe him, the sacrifice and oblation to Jesus will cease and will be transferred to him, the pretender to the throne.
Read the prayer Daniel made in the beginning of the chapter. His prayer was for forgiveness of the Jews, and the people of Israel who had rebelled, and for the actual city of Jerusalem which was in ruins at the time. The angel was sent with an answer to Daniel's prayer concerning his people and the city.
Dan 9:1 In the first year of Darius the son of Ahasuerus, of the seed of the Medes, which was made king over the realm of the Chaldeans;

Dan 9:3 And I set my face unto the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes:
Dan 9:4 And
I prayed unto the LORD my God, and made my confession, and said, O Lord, the great and dreadful God, keeping the covenant and mercy to them that love him, and to them that keep his commandments;
Dan 9:5
We have sinned, and have committed iniquity, and have done wickedly, and have rebelled, even by departing from thy precepts and from thy judgments:
Dan 9:6
Neither have we hearkened unto thy servants the prophets,
which spake in thy name to our kings, our princes, and our fathers, and to all the people of the land.
Dan 9:7 O Lord, righteousness belongeth unto thee, but unto us confusion of faces, as at this day;
to the men of Judah, and to the inhabitants of Jerusalem, and unto all Israel, that are near, and that are far off, through all the countries whither thou hast driven them, because of their trespass that they have trespassed against thee.
Dan 9:8
O Lord, to us belongeth confusion of face, to our kings, to our princes, and to our fathers, because we have sinned against thee.
Dan 9:9 To the Lord our God belong mercies and forgivenesses, though
we have rebelled against him;
Dan 9:10
Neither have we obeyed the voice of the LORD our God, to walk in his laws, which he set before
us by his servants the prophets.
Dan 9:11
Yea, all Israel have transgressed thy law, even by departing, that they might not obey thy voice;
therefore the curse is poured upon us, and the oath that is written in the law of Moses the servant of God,
because we have sinned against him.
Dan 9:12 And he hath confirmed his words, which he spake against us, and against our judges that judged us, by bringing upon us a great evil:
for under the whole heaven hath not been done as hath been done upon Jerusalem.
Dan 9:13 As it is written in the law of Moses,
all this evil is come upon us: yet made we not our prayer before the LORD our God, that we might turn from our iniquities, and understand thy truth.
Dan 9:14 Therefore hath the LORD watched upon the evil, and brought it upon
us: for the LORD our God is righteous in all his works which he doeth: for
we obeyed not his voice.
Dan 9:15 And now, O Lord our God, that hast brought thy people forth out of the land of Egypt with a mighty hand, and hast gotten thee renown, as at this day; we have sinned, we have done wickedly.
Dan 9:16 O Lord, according to all thy righteousness,
I beseech thee, let thine anger and thy fury be turned away from thy city Jerusalem, thy holy mountain: because for our sins, and for the iniquities of our fathers, Jerusalem and thy people are become a reproach to all that are about us.
Dan 9:17 Now therefore, O our God, hear the prayer of thy servant, and his supplications, and
cause thy face to shine upon thy sanctuary that is desolate, for the Lord's sake.
Dan 9:18 O my God, incline thine ear, and hear; open thine eyes, and
behold our desolations, and the city which is called by thy name: for we do not present our supplications before thee for our righteousnesses, but for thy great mercies.
Dan 9:19 O Lord, hear; O Lord, forgive; O Lord, hearken and do; defer not, for thine own sake, O my God: for thy city and thy people are called by thy name.
Dan 9:20
And whiles I was speaking, and praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before the LORD my God for the holy mountain of my God;
Dan 9:21 Yea, whiles I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation.
And the angel said
Dan 9:22 And he informed me, and talked with me, and said, O Daniel, I am now come forth to give thee skill and understanding.
Dan 9:23 At the beginning of thy supplications the commandment came forth, and I am come to shew thee; for thou art greatly beloved: therefore understand the matter, and consider the vision.
Dan 9:24
Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
The rest of the chapter has to do with the nation of Israel, the literal city of Jerusalem, and the actual temple that was in the city. Lol
Daniel prayed for his people and his city, and God answered him as to what would happen to his people, and to the city and temple. The answered prayer has nothing to do with the church. Daniel wasn't asking for forgiveness for the church. He asked for the people of Israel then living. :yes
