Jeremiah 52:10-11

10He told his soldiers to kill all Zedekiah's sons, while Zedekiah watched. He also punished all the officers of Judah with death there at Riblah.

11Then they cut out Zedekiah's eyes to make him blind. They tied him with chains and they took him to Babylon as their prisoner. They kept him in prison until the day that he died.
