You are not naive. What's the reason for Zech 6:13 then? Why, as you say, crown Joshua symbolically instead of just leaving the space blank until Christ? It makes no sense, literal nonsense! Zech 6:13 specifically tells you he reigned and built the temple post-Babylon. Your excuse is but an excuse.
Zechariah 6:13 and all of the prophecies about Jesus in the old testament (tanach) were to validate that he is the true messiah..... because God foretold about Jesus ahead of time.... including his (Hebrew) name. But the gospel that Jesus would die for the sins of mankind was sealed from "understanding" until after resurrection - although Jesus told the disciples what would take place ahead of time. We see this in Luke 18.... as they were about to enter Jerusalem that last passover week.
31Then he took
unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished.
32For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on:
33And they shall scourge
him, and put him to death: and the third day he shall rise again.
34And
they understood none of these things: and t
his saying was hid from them, neither knew they the things which were spoken.
An then later
after the resurrection, and Jesus appeared to them in his resurrected body, we see in Luke 24, that Jesus
opened the disicples "understanding" of what he had told them aforehand. And "understanding" all of the prophecies in the Tanach (which is a Jewish acronymn for the law (the first five books of the bible), the prophets, and the writings (psalms, proverbs).
my comment in brackets...
44And he said unto them, These
are the words which I spake unto you, while I was yet with you
[that is, before Jesus being crucified], that all things must be fulfilled, which were written in the law of Moses, and
in the prophets, and
in the psalms,
[the Tanach] concerning me.
45Then opened he their understanding, that they might understand the scriptures, 46And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
47And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
So why was everything kept a mystery, that no-one understood ahead of time? Which the Jews (Judaism) still in their objection to Christianity say we don't read anything in our Tanach of the messiah would die for the sins of mankind so that we would have eternal life.
We can only put together the pieces as to why the understanding of the pieces of the prophecies about the messiah were shrouded in a mystery - until after the resurrection and Jesus opened the disciples understanding, by divine power. We are given clues in 1Corinthians2 as to why the mystery.
7But we speak the wisdom of God in a mystery,
even the hidden
wisdom, which God ordained before the world unto our glory:
8Which none of the princes of this world knew:
for had they known it, they would not have crucified the Lord of glory.
So the question becomes who would have thought that they would benefit by Jesus being killed, crucified ?
It is Satan, the chief prince of this world. Satan thought by having Jesus crucified, that would prevent the Kingdom of God from replacing his own kingdom from ruling over the earth. The other question becomes why doesn't God just destroy Satan?
The reason is it appears that Satan basically in the garden of eden got Adam and Eve to fall into sin - as means to keep God from destroying him as he had already rebelled by aspiring to ascend above God. When man fell to sin, that meant by equal justice, God would likewise have to destroy all mankind for our sins as well - if He were to destroy Satan. So Satan by self survival wants to keep man a hostage to sin.
But Satan came out in hindsight to the crucifixion - looking like a fool. The very thing that he had leveraged his survival on -
man being forever guilty of sin - was done away with by Jesus's death taking those sins away from us.
So we can see why the prophecies about Jesus in the Tanach were kept shrouded in a mystery. It was to keep Satan from knowing ahead of time from doing the very thing - that would free God up from carrying out prosecution, judgment, and destruction of Satan - without destroying all of mankind equally for our own sins.
In Revelation 11, the sounding of the 7th trumpet announces the forthcoming procecution of Satan as being prince of this world. He will be cast down to earth, his kingdom overshadowing the earth fallen, has fallen - Babylon has fallen, has fallen.
That event is forthcoming halfway through the final 7 years.
Zechariah 6, as the other prophecies about Jesus in the Tanach, are there to validate that Jesus is the true messiah, that's why they are there. But they have been shrouded in mystery, which by reading from the Tanach only, they can never be understood. And still cannot be understood except by the divine power of the Holy Spirit to understand them.
44And he said unto them, These
are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and
in the prophets, and
in the psalms, concerning me.
45Then opened he their understanding, that they might understand the scriptures,
46And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
47And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
48And ye are witnesses of these things.
49And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
