Ezekiel 43:6-12 New King James Version (NKJV)
6 Then I heard Him speaking to me from the temple, while a man stood beside me. 7 And He said to me, “Son of man, this is the place of My throne and the place of the soles of My feet, where I will dwell in the midst of the children of Israel forever. No more shall the house of Israel defile My holy name, they nor their kings, by their harlotry or with the carcasses of their kings on their high places. 8 When they set their threshold by My threshold, and their doorpost by My doorpost, with a wall between them and Me, they defiled My holy name by the abominations which they committed; therefore I have consumed them in My anger. 9 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. 12 This is the law of the temple: The whole area surrounding the mountaintop is most holy. Behold, this is the law of the temple.
Once again please note that the temple is God's idea and not Babel. YHWH wanted/will is keeping of the temple ordinances.
Somebody the other day suggested that the temple will be built right up before Rapture,and 3.5 years after Rapture AntiChrist defiles it and then tribulation begins.
This is all fancy but it does not explain the purpose the temple will be serving BEFORE. Why would God direct Jews away from Calvary from Melchizedek and back to Levi only for Antichrist to come and rain on the parade?
Note the verse 9 condition. God would do X if Israel did Y
