The events of Daniel 11 were such an accurate description of the abominations of Anthiochus that critical theologians assert that Daniel was written
after the events.
The Thessalonians were obviously confused about the comings of Jesus that Paul had to explain in detail in 2T2 that the final coming for resurrection, vindication & judgment would be preceded by the destruction of the temple as prophesied by Jesus in his Olivet prophecy. Paul has already explained, & makes himself clear. The final coming, will at an unknown date some time after the destruction of the then existing temple.
Note 1T2 -
14 For you, brethren, became imitators of the churches of God which are in Judea in Christ Jesus. For you also suffered the same things from your own countrymen, just as they did from the Judeans,
15 who killed both the Lord Jesus and their own prophets, and have persecuted us; and they do not please God and are contrary to all men,
16 forbidding us to speak to the Gentiles that they may be saved, so as always to fill up the measure of their sins; but wrath has come upon them to the uttermost.
As for Ezekiel's temple, that prophecy was made during the Babylonian captivity. THe Israelites were being encouraged to rebuild the temple on their return, and to be faithful to their LORD. Read ch 43 which describes animal sacrifices as sin offerings. NOT memorial offerings as some contributors have claimed.
43:10 “Now let them put their harlotry and the carcasses of their kings far away from Me, and I will dwell in their midst forever.
10 “Son of man, describe the temple to the house of Israel, that they may be ashamed of their iniquities; and let them measure the pattern.
11 “And if they are ashamed of all that they have done, make known to them the design of the temple and its arrangement, its exits and its entrances, its entire design and all its ordinances, all its forms and all its laws. Write it down in their sight, so that they may keep its whole design and all its ordinances, and perform them.

18 And He said to me, “Son of man, thus says the Lord GOD: ‘These are the ordinances for the altar on the day when it is made, for sacrificing burnt offerings on it, and for sprinkling blood on it.
19 ‘You shall give a young bull for a sin offering to the priests, the Levites, who are of the seed of Zadok, who approach Me to minister to Me,’ says the Lord GOD.
Ezekiel's temple was obviously an idealised description of the temple to be built on their return from exile. A future third temple for the offering of sacrifices for sin would utterly violate the FINISHED sacrificial death of our LORD Jesus Christ.
Eze. 43:10 “Now let them put their harlotry and the carcasses of their kings far away from Me, and I will dwell in their midst forever.
Contrast this with -
Rev. 21:3 And I heard a loud voice from heaven saying, “Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God.

22 But I saw no temple in it, for the Lord God Almighty and the Lamb are its temple.
