Jeremiah 52:1-5

Zedekiah was twenty-one years old when he became king, and he reigned for eleven years in Jerusalem; and his mother’s name was Hamutal the daughter of Jeremiah of Libnah.

He did evil in the sight of the Lord, in accordance with everything that Jehoiakim had done.

For because of the anger of the Lord this came about in Jerusalem and Judah, until He drove them out from His presence. And Zedekiah revolted against the king of Babylon.

Now it came about in the ninth year of his reign, on the tenth day of the tenth month, that Nebuchadnezzar king of Babylon came, he and all his army, against Jerusalem, camped against it, and built a bulwark all around it.

So the city was under siege until the eleventh year of King Zedekiah.
