Jeremiah 52:27-30

27There at Riblah in the land of Hamath, the king of Babylon struck them down and put them to death. So Judah was taken into exile, away from its own land.

28These are the people Nebuchadnezzar carried away:

in the seventh year, 3,023 Jews; 29in Nebuchadnezzar’s eighteenth year, 832 people from Jerusalem; 30in Nebuchadnezzar’s twenty-third year, Nebuzaradan captain of the guard carried away 745 Jews.

So in all, 4,600 people were taken away.
