It’s mentioned in Revelation (as posted above) and the temple will be rebuilt. I think the fact that the curtain separating the ark was torn on the day Jesus died has significance to Him at least.
Perhaps it’s worth mentioning that another name for the ARK given in the bible is “Ark of the testimony”. The Ark was/is to remain as a testimony to b recovered/uncovered in the last days as an absolute testimony of God and his dealings with the Hebrews.
There is a passage in the bible which states that truth shall spring forth from the earth in the last days. This believed to relate to the reappearance of the Ark and the testimony that it brings of God.
It has been considered that it is this testimony which brings the Jews back to their faith and reconciles them to God from whom many have departed.
It might also be construed that the Truth which springs forth from the Earth might also/or relate to Christ Himself who is the embodiment of the Holy Spirit who is also called “The Spirit of Truth”.
Perhaps the bible references relating to the truth springing forth from the Earth like many biblical prophecies has dual meanings and can correctly be applied to the recovery of the Ark and other Temple treasures as well as referring to Christ.
Both references when considered would have a very positive bearing on the Jews returning to God in the last days as foretold in the bible.
I am anxiously awaiting the recovery of the Ark if we are still around when that happens. That recovery might possibly precede the Rapture although it may also be withheld until after the Rapture to provide the justification for the Jews return to God and them taking up their ministry after the Rapture.
Regardless, these are certainly great and interesting times to be living in as a Christian expecting the soon return of the Lord.
