During the one week He will make a firm covenant with many. For half a week He will put a stop to the sacrifice and meal offering. At the corner [of the altar] will be appalling abominations until the decreed destruction will be poured down upon the appalling thing.
When Yahweh (God the Father) sent us His Son Jesus Christ He sent unto us the Truest Hallmark Card for the Father cared enough to send us the very best. So after Christ Jesus gave Himself as our final sin sacrifice what could be more appalling to the Father than to say even though Jesus was sacrifice for me to do away with sin once and for all, I'm going to honor Moses and offer animal sacrifices for my sin(s) --Hebrews 10:14-18; John 19:31.
IMO this is what the following verse describes:
Of how much sorer punishment, suppose ye shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant , wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of Grace?
The Book of Hebrews was written to Christian Jews, and when one looks at verse 28 in this 10th chapter where the writer compare Moses and the Law, to the New Covenant it seems to me the writer is stating that to try to add the Jewish Sacrifices of Moses to justify oneself before God was to count the blood of Christ an unholy thing.
Montana Marv, if one only reads Matthew's Gospel I could see this problem you are alluding too. But with the above passage in Daniel, along with a passage in Luke we can see that the early Jewish Christian did exactly as Jesus instructed. For in Daniel 9:27 in the Tanakh we see that their is a decree destruction upon this Abomination of Desolation, in other words it would not happen within the 70 weeks period nor be judge immediately. For is not this what Paul had stated to the Thessalonians in I Thessalonians 2:13-16. So than although this appalling thing of animal sacrifices after Christ's Resurrection was the Great Abomination of Desolation it had it own time period which ends would be mark by the following: And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Luke 21:20 This is the decree destruction upon the appalling thing. We also hear that at Jesus second Coming He will save Israel which I agree with, but if the Abomination of Desolation is in Jerusalem, when He returns where is the Time of the Gentiles spoken of in Luke 21:24 and how shall the Jew be led captive into all nations? In 70 AD just before the destruction of Jerusalem it was surrounded on every side by the Roman Legions, but around 66 AD after seeing signs of thee events to come most if not all Christian fled Jerusalem. Titus gave orders when the Romans finally took all of the city of Jerusalem not to harm the Temple, but because of frustration with the Jews the soldier burned down the Temple. The Romans had grew to hate the Jewish Rebels so much that they outright killed them (even woman and children) or led them captive among all the Nations, thus marking the Time of the Gentiles. In 1967, the Jews ended the Time of the Gentiles, by reclaiming the city of Jerusalem.
