What happened to the Ark of the Covenant? Is the ark mentioned in Revelation 11:19 the Ark of the Covenant that Moses made?
It is not likely that the original Ark of the Covenant ever survived the Babylonian destruction. The Ark is not mentioned as having gone into captivity. If we keep in mind that the Ark of the Covenant was basically a piece of wood overlaid with gold, Nebuchadnezzar would have only been interested in the gold. When the Jews returned from Babylonian captivity 70 years later, there was no Ark to put in the Temple they rebuilt. However, the Temple functioned just fine for six centuries without it. If the Jewish people could not find the Ark after 70 years, they are not likely to find it after 2,500 years.
The Ark of the Covenant in Revelation 11:19 is not the one that Moses made. We should keep in mind that what Moses made was a copy of the Ark that is already in Heaven. Besides, anything manmade cannot be translated to Heaven. The Ark in Revelation 11:19 is the heavenly one, the original from which Moses made a copy.
