In any event, you said that the Prince would come, and end the sacrificial worship system. Then you said, that the sacrificial system ended in 70ad. Doesn't that mean that the prince has already come?
In 9:27, Daniel says the Prince who comes out of those tribes will make a covenant with the many, Daniel's people, Israel, which will have a seven year term and at the mid point of the term, the Prince will cause the sacrifices and obliations to cease.
The sacrifices were last conducted in the spring of 70AD before the destruction; therefore a prophecy that says that at some future date, the sacrifices will be interrupted, of necessity implies that the sacrifices will need to be reinitiated so that they can be then later interrupted.
The question then before the house, is what has to happen before the sacrifices can be restarted. One thing is probably the Red Heifer.
