Jeremiah 52:2

Zedekiah was twenty-one years old when he began to reign. He reigned eleven years in Jerusalem. His mother’s name was Hamutal the daughter of Jeremiah of Libnah.

For through the LORD’s anger this happened in Jerusalem and Judah, until he had cast them out from his presence.

Zedekiah rebelled against the king of Babylon.

In the ninth year of his reign, in the tenth month, in the tenth day of the month, Nebuchadnezzar king of Babylon came, he and all his army, against Jerusalem, and encamped against it; and they built forts against it round about.

So the city was besieged to the eleventh year of King Zedekiah.
