(Is this speaking about during the thousand year kingdom?)

Jeremiah 3:16 And it shall come to pass, when ye be multiplied and increased in the land, in those days, saith the LORD, they shall say no more, The ark of the covenant of the LORD: neither shall it come to mind: neither shall they remember it; neither shall they visit it; neither shall that be done any more.

(Or did this already happen after the Babylonian captivity?

Will the ark be found again, after missing for 2600 years, since Nebuchadnezzar came against Jerusalem?

Will the ark be prominent in the tribulation temple?

Or is the ark, like Fay has mentioned, only in heaven, now?)
