Jeffro, for a Biblically based exegesis one takes the language as is: “He will pitch his royal tents between the seas toward the beautiful holy mountain. But he will come to his end, with no one to help him.” (Dan. 11:45 NET).
Take note, יַמִּ֖ים jammim “seas” (plural). What does it mean? Isaiah explains the symbolic use of “sea:” “But the wicked are like a surging sea that is unable to be quiet; its waves toss up mud and sand.” (Isa. 57:20; cf. 17:12). So, seas = people. Which mountain is he referring to? How about this one: “many peoples will come and say, "Come, let us go up to the LORD's mountain, to the temple of the God of Jacob, so he can teach us his requirements, and we can follow his standards." (Isa. 2:3; cf. Mic. 4:2). So the last King of the North will work hard to prevent people from reaching God’s symbolic mountain. Later we see, he will certainly fail.
But for your secular exegesis one needs “hyperbolic, open ended and superstitious phrasing” in order to force the meaning and vocabulary of the passage to fit your historical construction.The Maccabees also attempted to apply the book to their time (cf. Dan. 9:24-27). Jesus pointed out their mistake by applying the prophecy to the time of the Romans, to accurately reflect their actions.
So when we read the following, we don't have to revert to “hyperbolic, open ended and superstitious phrasing.” We take it quite literally:
The angel Gabriel informs Daniel: “Understand, O son of man, that the vision is for the time of [the] end” [“the end time,” NAB] (Dan. 8:17b). He continues: “Here I am causing you to know what will occur in the final part [’acharith] of the denunciation, because it is for the appointed time of the end.” The “final part of the denunciation” refers to God’s anger during “the time of the end” (Dan. 8:19, 25; 11:36; cf. Rev. 14:19; 15:1). The small horn/fierce king will rise “in the final part [’acharith] of their kingdom, as the transgressors act to completion” (cf. Dan. 8:23). The small horn/fierce king will come to his end “but not by human agency” (Dan. 8:25 NET; cf. Rev. 19:11-21). Gabriel concludes: “And the vision of the evening and the morning that has been told is true. And as for you, seal up the vision, because it is for many days” [“it concerns the distant future,” NIV].
