What did Nebuchadnezzar do with the temple vessels he carried away from Jerusalem?
Nebuchadnezzar carried the gold, silver, and brazen vessels from the house of God in Jerusalem to the land of Shinar, back to Babylon, and placed them in one of the temples of his gods. They were later brought out at Belshazzar's drunken feast for wine drinking and partying.
Les explains that in Daniel chapter 1, Nebuchadnezzar came to Jerusalem and besieged it, and the Lord gave the king of Judah into his hand along with part of the vessels of the house of God. He carried those vessels to the land of Shinar, back to Babylon, to the house of his god. In other words, he took all the gold, silver, and brazen vessels from Jerusalem back to Babylon and put them in one of the temples of his gods. Les suggests he got away with it because he probably didn't use them until the great drunken feast of Belshazzar, when they brought in the vessels and used them for wine drinking and partying. Then the handwriting on the wall appeared. All these vessels from that beautiful temple had been taken to Babylon.
In the third year of the reign of Jehoiakim king of Judah came Nebuchadnezzar king of Babylon unto Jerusalem, and besieged it.
