Midrasch zu Bereschit 47:17

R. Juda, in the name of Samuel, said: "All the silver and gold of the world Joseph accumulated and brought to Egypt, as it is said (Gen. 47, 17) And Joseph gathered up all the silver that was found in the land of Egypt. From this we infer that he accumulated only that of the land of Egypt; whence do we infer that he gathered up the silver and gold of Canaan and all other countries as well? It is therefore said (Ib. 57, 41) And all the countries came into Egypt. And when Israel went forth from Egypt they took along all this wealth, as it is said (Ex. 12, 36) And they emptied out Egypt." R. Simon b. Lakish said they left her like a net without gram. All this wealth was in Israel's possession until the days of Rehoboam, the son of Solomon, when Shishak, king of Egypt, invaded Jerusalem and took them away from Rehoboam, as it is said (I Kings 14, 25) And it came to pass in the fiftieth year of King Rehoboam that Shishak, the king of Egypt, came up against Jerusalem. And he took away the treasures of the house of the Lord, and the treasures of the king's house, yea, everything did he take away. And he took away all the shields of gold which Solomon had made. Then Zarah, the king of Ethiopia, invaded Egypt and took it away from Shishak, king of Egypt; later Assa, king of Israel, took it away from Zarah, king of Ethiopia, and sent it unto Hadrimon b. Tabrimon; and when the Ammonites invaded Syria they took it away from Hadrimon b. Tabrimon. Again Joshaphat came and took it from the Ammonites, where it remained until the days of king Achaz, when Sancherib came and took it away from Achaz. When Ezekiah fought Sennacherib, he took it away from him, and it remained with the former until the days of Zedekiah, when the Chaldeans invaded Judea and took it away from Zedekiah. The Persians later took it away from the Chaldeans, and Greece took it away from Persia. Finally the Romans came and took it away from Greece, and it is still hidden in Rome."
