How unspeakably terrible for the king to have to witness the death of his beloved sons. How terrible it is for the ungodly to see their children die at the hands of the enemy who came to steal, kill, and destroy—through drug or alcohol abuse, AIDS, or suicide due to guilt or hopelessness—because they refused to surrender to the Lord. The sins of the parents are often passed on to the children, who often pick up the same destructive behaviors.
Jeremiah 52:10 Then the king of Babylon killed the sons of Zedekiah before his eyes. And he killed all the princes of Judah in Riblah.11 He also put out the eyes of Zedekiah; and the king of Babylon bound him in bronze fetters, took him to Babylon, and put him in prison till the day of his death.
