The LORD had warned that someday the treasures would be taken from the royal palace and from the temple, including the gold objects that Solomon had made for the temple. And that's exactly what Nebuchadnezzar ordered his soldiers to do.
Nebuchadnezzar carried off everything that was left in the temple; he robbed the treasury and the personal storerooms of the king and his officials. He took everything back to Babylon.
The Lord let Nebuchadnezzar capture Jehoiakim and take away some of the things used in God's temple. And when the king returned to Babylonia, he put these things in the temple of his own god.
