You really can't imagine the Temple described by Ezekiel. The outer wall that fences off the area of the Lord's estate, in the center of which the temple complex is located, is 1440 meters long (500 reeds). Around this wall, along the perimeter, a trading area 24 meters wide (40 cubits) will be built.And how do you know this? Were you there in Zerubbabel's days as he was helping to build it from start to finish? Remember, Herod's temple renovations greatly changed what the Second temple looked like during those 46 years in building it, as of Christ's first Passover. Jerusalem's temple by then had become one of the wonders of the world at that time.
He measured the east side with the measuring reed, five hundred reeds, with the measuring reed round about.
He measured the north side, five hundred reeds, with the measuring reed round about.
He measured the south side, five hundred reeds, with the measuring reed.
He turned about to the west side, and measured five hundred reeds with the measuring reed.
He measured it by the four sides: it had a wall round about, five hundred reeds long, and five hundred broad, to make a separation between the sanctuary and the profane place.
(Ezekiel 42:16-20)
Of this there shall be for the sanctuary five hundred in length, with five hundred in breadth, square round about; and fifty cubits round about for the suburbs thereof.
(Ezekiel 45:2)

This entire area, measuring 1488x1488 meters, must be cleared of any extraneous buildings and graves. No one has ever built anything like this in Jerusalem and will never be able to do this - demolish all the buildings and graves in an area of 1.5 by 1.5 kilometers!
You stubbornly continue to talk about some position of high priest, which does not exist at all in the Temple described by Ezekiel. There will only be priests (Kohanim) and Levites.Zadok was not an imaginary person. And his family descendants were not imaginary. God specifically prohibited the other Levites and their families from serving as a high priest in that temple described in Ezekiel, because they became unfaithful during their Babylonian exile.
There should be no high priest in Ezekiel's Temple. Because the High Priest is now Jesus:Only the family of Zadok had remained faithful, and their reward was to be the only ones allowed to come near unto God and offer Him the fat and the blood, and to minister "in the MOST HOLY PLACE" (Ez. 44:13). To enter the Holy of Holies was the role of the high priest back then in Zerubbbel's days, when Joshua son of Josedech with his Zadok genealogy was set up as the high priest in the rebuilt Ezekiel temple.
Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec. (Hebrews 6:20)
Jesus fulfilled only that part of the law that was laid upon Him at the First Coming. He also did not fulfill many of the Old Testament prophecies that pertained to His Second Coming.Nobody said Christ abolished the law. He fulfilled it by becoming the prophesied High Priest after the order of Melchizedek - a superior order than that of the Levites.
For example, Jesus fulfilled only 3 of the seven feasts of the Lord at the First Coming:
1. Passover
2. Unleavened Bread
3. The First Sheaf
One more feast of the Lord was fulfilled by the Church:
4. Pentecost
There are 3 autumn feasts that remain unfulfilled for the Second Coming:
5. Yom Teruah
6. Yom Kippur
7. Sukkot (Simchat Torah, the 8th day of Sukkot)
These last three feasts will be fulfilled with the building of the Third Temple and the city of Yahweh Shammah.
The Temple will be built on a new site, which is determined by the prophecy of Ezekiel. The fact that the Second Temple was destroyed does not mean anything. The First Temple was also destroyed, and then the Second Temple was built, and on the same site.Christ Jesus is a priest forever after this superior order of Melchizedek. This was that "change in the law" which Hebrews 7:12 spoke of. "For the priesthood being changed, there is made of necessity a change also of the law." The Old Covenant died as soon as Christ established the New Covenant in His blood on His resurrection-day ascension. We know the OC and its rituals died then because Hebrews 8:13 says so. It was dead, and it was decaying, and it was ready to "vanish away", once God physically tore the whole system down to the last stone in AD 70 so that it would never be rebuilt again.
What "better things" are you talking about? How Christians have been fighting among themselves for thousands of years? Or how Christians have crucified the Body of Christ by thousands of denominations, building a Babylon where one denomination does not understand another denomination? Or how Christians have come up with the idea of putting an idol in the Temple instead of God, a pagan sun god, repainting it to look like Jesus Christ? Today's Judaism is simply a lamb of God compared to the predatory eagle of Christianity.It matters not that the Jews continued to offer sacrifices in memory of sin in their obsolete physical temple after Christ's death and resurrection. Those sacrifices had become replaced by "better things" at that point, and the apostle Paul warned believers not to return and submit to Judaism. Judaism and the temple was scheduled for a fiery ending which was about to devour the Jews in that first century Roman / Jewish war period.
"To scatter the power of the holy people" has not yet happened, the prophecy of Daniel refers to the future. The prophecy of 2300 evenings and mornings, the prophecy of 1290 days, the prophecy of 1335 days are still in the process of being fulfilled.Daniel 12:7 had predicted long ago that the power of the holy people would be shattered, and it was back in AD 70 .
