How does Jeremiah 52:9 connect to God's warnings in earlier chapters?

Jeremiah 52:9 records King Zedekiah’s capture by Nebuchadnezzar, the precise fulfillment of the Lord’s repeated warnings in earlier chapters (Jeremiah 21:8-10; 24:8-10; 25:8-11; 32:28-29; 34:2-3; 38:17-18) that Judah and her king would be handed over to Babylon if they refused to repent and surrender.
