The 70 week clearly prophesies of and finds its fulfillment in the new covenant and gospel
Daniel 9:24 “Seventy sevens are decreed about your people and your holy city, 1.) to finish the transgression, 2.) to put an end to sin, 3.) and to atone for iniquity, 4.) to bring in everlasting righteousness, 5.) to seal both vision and prophet, 6.) and to anoint a most holy.
All 6 items find their fulfillment in the 70th week, with the death of Christ. For it is Christ who was cut off in the midst of the week in order that the sacrifice and offering would be ended.
Hebrews 10:8-9 In the passage above He says, “Sacrifices and offerings, burnt offerings and sin offerings You did not desire, nor did You delight in them” (although they are offered according to the law). Then He adds, “Here I am, I have come to do Your will.”
He takes away the first to establish the second.
1.) finish transgression. God redeemed his people from the transgressions committed under the old covenant
Hebrews 9:15 Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.
2.) put an end to sin. Christ put away sin by his sacrifice
Hebrews 9:26 But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself.
3.) atone for iniquity. Christ is our high priest and atones for our sins.
Hebrews 2:17 or this reason He had to be made like His brothers in every way, so that He might become a merciful and faithful high priest in service to God, in order to make atonement for the sins of the people.
4.) Bring in everlasting righteous. The righteous standards of God have forever been fulfilled in those who are in Christ.
Romans 8:3-4 For what the law was powerless to do in that it was weakened by the flesh, God did by sending His own Son in the likeness of sinful man, as an offering for sin.
c He thus condemned sin in the flesh, so that the righteous standard of the law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.
5.) Sealing vision and prophet. Christ fulfilled everything written about him in the Law, prophets, and psalms.
Luke 24:44 Then he said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.”
6.) annoint the most Holy. Christ is the anointed most Holy.
Acts 10:38 how God anointed Jesus of Nazareth with the Holy Spirit and with power, and how Jesus went around doing good and healing all who were oppressed by the devil, because God was with Him.
