King Zedekiah attempted to flee that final siege, and was captured and taken prisoner. He saw his sons slaughtered before his eyes, his own eyes were then burned out with red hot irons and he was taken away in chains to prison and exile.
Jeremiah 52: 10 There at Riblah the king of Babylon slaughtered Zedekiah’s sons before his eyes, and he also killed all the officials of Judah
