Prior chapters of Ezkiel, from 40 up to 46 seem to be describing a temple that was built prior to Jesus time. However, chapter 47 seems to be a future temple in that the waters flowing from it are like the living water mentioned in Revelation. I only say that because it says that wherever this water flows, everything will live and the Dead Sea will be made fresh, with only the marshes and swamps being left salty. I am not aware of this happening in the past. Also, there will be many trees along the banks and like the tree of life they will bear fruit once a month(for food) and the leaves will be used for medicine, like the tree of life. This sounds like a more detailed description of the account in Revelations. How do you see this chapter?
Yes, those Ezek.40 thru 48 chapters are covering points starting at Christ's future "thousand years" reign and into the new heavens and a new earth, which Rev.21 & 22 does also.
I don't believe the animal sacrifices it mentions are literal though. I believe that was written because of the time that prophecy was given to Ezekiel during the old covenant. Just that point alone has made many to mistake it for past history. At the end of Revelation, we are shown there eventually will be no temple, which is new heavens and new earth timing. I equate the last verse of Ezek.48 "The LORD is there" being the name of the city with new heavens and new earth timing.
Rev.22:14-15 reveals the wicked still existing outside the gates of the holy city while Christ's elect inside have right to the waters and tree of life, so that is a direct parallel to those Ezekiel events. Revelation 21 & 22 does not reveal the exact location of the holy city, while Ezekiel 40-48 does, i.e., on earth in the area of today's Jerusalem, the Waters being mentioned in relation to Engedi in the middle east.
In Genesis 2, we are shown about God's River once being upon this earth, flowing out of Eden to water four other rivers on the earth, of which three of them are known locations (river Gihon in Ethiopia, Hiddekel which is the Tigris, and Euphrates which those two still exist today).
So by this Biblical evidence, it reveals where God's Kingdom will manifest in the future, upon this earth and not in the clouds, for He did say in Isaiah that He created the earth to be inhabited (lived upon). That tears down the belief of certain denominations that think the earth will be totally destroyed and His Kingdom will be up in the clouds only. The cube of Revelation will reach up 1500 miles off the earth, but its base will be on the earth, with peoples living upon this earth, building houses and planting vineyards per Isaiah. Because of their traditions of men, I think those certain denominations place these Scripture evidences as past history when they have yet to occur.
