Christian and Mystic, “the ark of His covenant that appeared in His temple”, 'what is the ark of His covenant?

It is a box that was covered in gold that had two angels on the top of it whose wings touched each other. Inside was Aaron's rod that budded, a jar of manna, and the tablets Moses carved. It had rings on the corners that two rods were passed through so the priests could carry it. They were not allowed to touch the ark. One man did and it killed him. We don't know where the ark is now, there are several theories, but the one that is in heaven is the original. The one on earth was a copy.
