What is your understanding of "And he shall confirm the covenant with many for one week" referred to in Daniel 9:27?
When Israel returned to the promised land after the 70 years captivity, God said they would have to continue to pay the price of rebellion for 490 years. This would be completed when Jesus returned and ruled the world for 1000 years from David's throne.
Jeremiah 31 speaks of a new covenant that God would establish {please go and read the details}.
When God said he would establish a new covenant, it was a done deal. The only question is when it would be confirmed with the blood of a sacrifice.
God also said that after 483 years He would send the Messiah, the Prince, who would be cut off after three and a half years.
This was fulfilled at the baptism of Jesus when it was announced from Heaven that "This is my Son".
"HE", the Messiah the Prince, (Jesus) immediately began to confirm the new covenant with many just as verse 27 states.
If you will remember, Jesus only went to the Jews and instructed His disciples to do the same.
While Israel as a nation rejected the new covenant, many Jews accepted it.
HE, the Messiah the prince, would be cut off in the mist (near the middle) of the 70th week when HE went to the cross to seal the new covenant with His blood.
When Jesus died on the cross He said "It is finished". The new covenant was sealed with His blood.
With the new covenant non sealed, the need for the sin (animal) sacrifices was not longer needed or was it accepted by the Father.
To continue to offer sacrifices was an abomination to God because if was open rebellion against the new covenant that had been sealed with the blood of His son.
This abomination is what brought about the judgment of Jerusalem, the temple, and the nation being totally destroyed at the hand of the "people of the prince"( Vespasian's army under the comm and of his son Titus).
Daniel 12 speaks of 1290, and 1260 days remaining from the death of Jesus until He returns to rule from David's throne for 1000 years. This is the last half of the 70th week.
I believe the 1290 is the time of the anti-christ from the time he is identified (when he stand up after the head wound) until Jesus returns.
I believe 1260 is the time that Israel is in the wilderness protected by God for 1260 days and coincides with the time the anti-christ makes war on the saints.
The 1335 days is the time from the identifying of the antichrist until the the completion of the seals, trumps and bowls, with the seven bowls of God's wrath being poured out during the last 45 days of the 1335 after Jesus returns.
I am sure most if not all will disagree, but that is my understanding.
The point is that the anti-christ will come.
He will bring great tribulation.
Jesus will return, the anti-christ and the false prophet will be cast into the lake of fire.
God's wrath will be poured out on the wicked.
Jesus will rule from David's throne for 1000 years.
