2 Samuel 12:30; 2 Samuel 12:31

30 Then he took the crown of their king from his head; and its weight was a talent of gold, and in it was a precious stone; and it was placed on David's head. And he brought out the spoil of the city in great amounts.

31 He also brought out the people who were in it, and set them under saws, sharp iron instruments, and iron axes, and made them pass through the brickkiln. And thus he did to all the cities of the sons of Ammon. Then David and all the people returned to Jerusalem.
