"He shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease..." Daniel 9:27.

Oblation /ObĚla┤tion/ (?), n. [L. oblatio: cf. F. oblation. See Oblate.]
1. The act of offering, or of making an offering. Locke.
2. Anything offered or presented in worship or sacred service; an offering; a sacrifice.
Covenant /Cov┤eĚnant/ (k?v┤?-nant), n. [OF. covenant, fr. F. & OF. convenir to agree, L. convenire.]
1. A mutual agreement of two or more persons or parties, or one of the stipulations in such an agreement.

First lets see who confirms the covanant.

Lets use the bible to interpret this. Turn to Matthew 26:28
"For this is my blood of the new testament, which is shed for many for the remission of sins."

That is the covenant confirmed, New Testament, with many.
Turn to Romans 15:8.
"Now I say that Jesus Christ was a minister of the circumcision for
the truth of God, to confirm the promises made unto the fathers:"
Turn to Galatians 3:17
"And this I say, that the covenant, that was confirmed before of
God in Christ
,... "
You see, Jesus Christ Confirms the covenant with the sacrifice that he made for us on the cross.

Now what is the oblation that is caused to cease?

The sacrifice that occured before the fulfillment of Daniel 9:27 was the Mosaic sacrifice. Moses, the leader of the Israelites, established through his agency, the Mosaic law, rites, and institutions given to him by GOD. But once Jesus Died on the cross, our sins were atoned for leaving no room or warrant for the continuation of any other sacrifice. The continuation of any other sacrifice would be the denial of Jesus Christ's propitiation.

Am I the only one who Believes this?

Actually I am not.
Matthew Henery wrote in "Mathew Henrey's Concoise Commentary on the Whole bible" refering to Daniel 9:27
"This seals the sum of prophecy, and confirms the covenant with many; and while we rejoice in the blessings of salvation, we should remember what they cost the Redeemer. How can those escape who neglect so great salvation!"

The Geneva Bible Translation Notes, refering to "...he shall cause the sacrifice and the oblation to cease...", read as such,
"Christ accomplished this by his death and resurrection."

John Calvin States in "COMMENTARIES ON THE PROPHET DANIEL BY JOHN CALVIN" concerning Dan 9:27:
Now, therefore, we understand why the angel says, Christ should confirm the covenant for one week, and why that week was placed last in order. In this week will he confirm the covenant with many.

John Wesley states in "John Wesley's Notes on the Bible"
Verse 27. He shall confirm - Christ confirmed the new covenant,
1. By the testimony of angels, of John baptist, of the wise men, of the saints then living, of Moses and Elias.
2. By his preaching.
3. By signs and wonders.
4. By his holy life.
5. By his resurrection and ascension.
6. By his death and blood shedding. Shall cause the sacrifice to cease - All the Jewish rites, and Levitical worship. By his death he abrogated, and put an end to this labourious service, for ever. And that determined - That spirit of slumber, which God has determined to pour on the desolate nation, 'till the time draws near, when all Israel shall be saved.

The "Jamieson, Faussett, and Brown Bible Commentary" states the following of Dan 9:27 :
"27. he shall confirm the covenant--Christ. The confirmation of the covenant is assigned to Him also elsewhere. Isa 42:6, "I will give thee for a covenant of the people" (that is, He in whom the covenant between Israel and God is personally expressed); compare Lu 22:20, "The new testament in My blood"; Mal 3:1, "the angel of the covenant"; Jer 31:31-34, describes the Messianic covenant in full. Contrast Da 11:30, 32, "forsake the covenant," "do wickedly against the covenant."
Adam Clark wrote in "Clarks Commentary" thus refering to Dan 9:27...
From the coming of our Lord, the third period is to be dated, viz., "He shall confirm the covenant with many for one week," that is seven years, ver. 27.
