Jeremiah 39:5-6
39:5 But the Babylonian army chased after them. They caught up with Zedekiah in the plains of Jericho and captured him. They took him to King Nebuchadnezzar of Babylon at Riblah in the territory of Hamath and Nebuchadnezzar passed sentence on him there.
39:6 There at Riblah the king of Babylon had Zedekiah’s sons put to death while Zedekiah was forced to watch. The king of Babylon also had all the nobles of Judah put to death.
