If they run into a large menorah and a funny-looking arc, kindly return to its owners.
Be careful moving the arc.
Amein!
Gibbon says that the menorah is at the bottom of the Med. Someone ought to go looking for it.
the prophet [Jeremiah], 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 Jeremiah came and found a cave-dwelling, and he brought there the tent and the ark and the altar of incense; then he sealed up the entrance. 6 Some of those who followed him came up intending to mark the way, but could not find it. 7 When Jeremiah learned of it, he rebuked them and declared: “The place shall remain unknown until God gathers his people together again and shows his mercy. 8 Then the Lord will disclose these things, and the glory of the Lord and the cloud will appear, as they were shown in the case of Moses, and as Solomon asked that the place should be specially consecrated.”
This is referring to the time of the Babylonian conquest, ca 587 BC.
As for the items looted from the Temple by Titus, I'm afraid the medieval rabbi who said they were in Rome was mistaken. They were probably melted down and used to pay for, e.g., the Colosseum, etc. One story says that they were sent back to Jerusalem by Constantine or by his successor (Julian the Apostate, who wanted to rebuild the Temple), but were re-looted from Jerusalem by the Persian Sasanians in 614 AD.

If it’s there (and it isn’t), then it’s already in the hands of its proper owners at this stage.
