However, generally there are hints that a person, place, thing, or event is symbolic of something else

Generally speaking, it will say things which only fit
the ultimate fulfillment.

An example of this is the prophecy of a son of David who will build a temple of the Lord, in 2Sam 7:12-16. Solomon is the immediate subject of this prophecy, and he did build a literal temple in Jerusalem in the 10th century BC. Still Solomon is symbolic of Jesus who is now building a spiritual temple for God. The tip off is the parts of this prophecy which really DO NOT FIT SOLOMON! Parts of this prophecy only fit Solomon, and parts only fit Jesus, and parts fit both, but in different ways. There is a complete discussion of this prophecy in Prophecy Principles, in the section called “Type and Anti-Type, Symbol and Fulfillment.

Another example is Antiochus IV and the mysterious
“abomination of desolation.”

Many different kings are spoken of in the prophecies of Daniel. Some of them are very easy to identify, for instance Nebuchadnezzar king of Babylon in Dan 2:38, and Alexander the Great and the four Greek kings who succeeded Alexander in Dan 8:20-22. Others require more research. It seems that Antiochus IV Epiphanes (215-163 BC) is clearly described in more than one place in Daniel’s writing, including Dan 11:21, 27-35. Antiochus IV tried to force Greek paganism on the Jews, and spectacularly failed. He put an idol of “Zeus” in the temple in Jerusalem, and offered a pig as a sacrifice on the altar there. This is described in the these prophecies as “the abomination of desolation,” Dan 11:31, etc. Idols are commonly called an abomination to God in the Old Testament. These are well known events in ancient history.

Then come the “problems” with these prophecies.

For also clearly, not everything ascribed to “Antiochus IV” happened in ancient times, especially Dan 11:36-45. Nor does everything said about “the abomination of desolation” fit the events in those same days. These are signs of either 1.) a false prophecy, as many liberal argue, or 2.) Antiochus IV is symbolic of some other ruler who will come later, and parts of these descriptions fit Antiochus IV, and parts fit someone else in later times! When?

Then Jesus makes the mystery even deeper.

Jesus clearly speaks in Matthew 24 of both the destruction of Jerusalem in 70 AD, and the end of the world, and says,

““When, therefore, you see the abomination of desolation, which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand),”
Mtt 24:15 WEB

So Jesus does indicate the idol of “Zeus” was also symbolic … and part of what He says will happen, clearly DOES NOT fit 70 AD! Keep in mind that Matthew 24 talks about TWO subjects!

These issues are described in much more detail in both Prophecy Principles, and in Revealing the Christian Age.

God evidently WANTS US to HAVE TO think out these
things in order to understand them.
