And it came to pass when the letter came to them, that they took the king's sons, and slaughtered seventy persons, and put their heads in baskets, and sent them to him to Jizreel.

and slaughtered the sons of Zedekiah before his eyes, and put out the eyes of Zedekiah, and bound him with chains of brass, and carried him to Babylon.
