No argument from me that the temple described was not the one destroyed in 70ad.
This “temple” is spiritual and describes the heavenly Jerusalem. Ch43 v7 says God will dwell in the midst of the people of Israel forever. This can not be an earthly temple.
So there is going to be burnt offerings in the temple in heavenly Jerusalem? Who knew? I wonder where the animals will be raised and the grain grown. And then all the land around the temple. Do you suppose their is land in heaven?
