Талмуд к Бамидбар 17:23

When the ark was hidden, there were hidden with it the flask of Manna, the bottle of anointing oil, Aaron’s staff with its almonds and flowers, and the chest which the Philistines returned as a reparation sacrifice for Israel’s God. Who hid it? Josiah hid it. When he saw that it was written: The Eternal will lead you and your king whom you will have put above you, to a people whom neither you nor your fathers had known, he started and hid it. That is what is written: He said to the Levites, who instruct all of Israel, the ones holy to the Eternal, put the Ark into the House that Salomon, son of David, King of Israel, built; you do not have to carry it on your shoulder.” He said, if it is exiled with you to Babylonia, you will never return it to its place. But now, serve the Eternal, your God, and his people Israel.

These are the things that were made and then hidden: The Tent of Meeting, and the items inside it; the Ark and the broken tablets; the jar of manna; the rod [of Moses]; [the flask of anointing oil]; the staff of Aaron, with its almonds and flowers; the priestly garments and garments of the high priest. But the mortar and pestle of the House of Avtinus, the table, the lamp, the curtain, and the headband of the high priest – those are still kept in Rome.
