1 One finds in the records that Jeremiah the prophet ordered those who were being deported to take some of the fire, as has been told, 2 and that the prophet after giving them the law instructed those who were being deported not to forget the commandments of the Lord, nor to be led astray in their thoughts upon seeing the gold and silver statues and their adornment. 3 And with other similar words he exhorted them that the law should not depart from their hearts.
4 It was also in the writing that the prophet, having received an oracle, ordered that the tent and the ark should follow with him, and that he went out to the mountain where Moses had gone up and had seen the inheritance of God. 5 And Jeremiah came and found a cave, and he brought there the tent and the ark and the altar of incense, and he sealed up the entrance. 6 Some of those who followed him came up to mark the way, but could not find it. 7 When Jeremiah learned of it, he rebuked them and declared: “The place shall be unknown until God gathers his people together again and shows his mercy." (2 Maccabees 2:1-7)
19 Then God’s temple in heaven was opened, and the ark of his covenant was seen within his temple; and there were flashes of lightning, loud noises, peals of thunder, an earthquake, and heavy hail. 1 And a great portent appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars. (Revelation 11:19--12:1)
Exactly so! The 2nd chapter of the 2nd book of Maccabees tells WHERE the Old Testament Ark of the Covenant was hidden. According to the Bible passage cited above, the Old Testament Ark of the Covenant is in a covered-up cave on Mt Nebo in the Kingdom of Jordan, coordinates 31.765095 degrees N by 35719079 degrees E, just NE of the Dead Sea. It was carried just over 24 miles from Jerusalem, when Jerusalem was about to be conquered & destroyed, including the 1st Temple, by the Babylonians, about 586 BC. Q.E.D.
