He shall seduce with flattery those who violate the covenant, but the people who know their God shall stand firm and take action.
All throughout the history of Israel there have been a faithful few who were part of the remnant who kept to the covenant. Daniel was living proof of this during the captivity. And now he is receiving remarkable revelation about the future of his people. And they will still suffer under invasion and persecution.
The text has two futures in view. One is clearly descriptive of the events we now know as the Maccabean Revolt. In this series of events the Greek overlords led by Antiochus Epiphanes (who believed himself to be a god manifest on earth) resulted in the temple being defiled as Antiochus brutally tried to eradicate Judaism and the worship of Yahweh.
But there is a more distant frame of time in mind as the text keeps referring to the mysterious and ominous "appointed time of the end". In fact, all the details mesh with Maccabean history as we know it until we get to Daniel 11:40-45. And then we are clearly looking at an event unknown yet in Jewish history. That is why plain hermeneutics conclude that this passage must be paralleled in events yet to come in Israel. And that is what dispensationalists attempt to explain. I think it is the plain way that best understands the text. And I also think there is no way I fully understand all the details stated here. As yet we cannot identify the key players in these events. But I am convinced it will all come into fruition just as God has said that it would.
