2 Chronicles 36:18-20
18-20And then he plundered The Temple of everything valuable, cleaned it out completely; he emptied the treasuries of The Temple of God, the treasuries of the king and his officials, and hauled it all, people and possessions, off to Babylon. He burned The Temple of God to the ground, knocked down the wall of Jerusalem, and set fire to all the buildings—everything valuable was burned up. Any survivor was taken prisoner into exile in Babylon and made a slave to Nebuchadnezzar and his family. The exile and slavery lasted until the kingdom of Persia took over.
21This is exactly the message of God that Jeremiah had preached: the desolate land put to an extended sabbath rest, a seventy-year Sabbath rest making up for all the unkept Sabbaths.
