I must say this is an interesting way of looking at this.
Don’t forget, however, that Judaism does not count the Book of Daniel as a book of prophecy or Daniel as one of the prophets.
In the Hebrew Scriptures the Book of Daniel is included among Ketuvim (כְּתוּבִים, “Writings”) such as the Psalms, Proverbs, Job, etc. It is not a part of the Nevi’im (נְבִיאִים, “Prophets”) such as Isaiah, Ezekiel, Malachi, etc.
Judaism recognizes 55 prophets, and Daniel is not one of them.
While his writings include visions of the future, they are a narrative of “visions” or “dreams.” Daniel never receives actual oracles or proclamations of the Lord to declare aloud to the people like the other prophets do. The Jews believe that his visions were designed to be written down to teach lessons to future generations. Their reason for including it in the canon was to preserve these lessons among the “Writings,” and not keep the book because it was a collection of prophecies waiting for their fulfillment.
Besides if one claims that chapter 4 is a prophecy, then why isn’t chapter 3 a prophecy too or chapter 6 or 5? If this is supposed to be a book of prophecy, then aren’t all the chapters laden with some prophetic meaning? Why only chapter 4?
And then why claim something about the book that the Jews don’t claim? If the Jews are wrong about the book of Daniel, then why consider it a part of word of God in the first place? If we accept that it is part of the word of God because of its origin in Jewry, should we not accept that it is not intended to be a book of prophecy? And if somehow we still want to demand chapter 4 to be prophecy, then how does one justify these non-Jewish delineating definitions about Daniel and on what authority?
Can you hear what this person is proposing: “Chapter 4, though not a book not considered prophetic by the Jews, is nevertheless truly a prophecy with two fulfillments!”
If the Jews say it isn’t prophetic, then who does? Who gave these other persons such an authority?
And if it is prophetic, why only two (2) fulfillments? Why not more? Why more than one? If it is a prophecy for “all people,” then what keeps it from being fulfilled in various ways for each and every individual who is living now or has ever lived?
Just some more to think about.
