Jeremiah 36:23-24
36:23 As soon as Jehudi had read three or four columns of the scroll, the king would cut them off with a penknife and throw them on the fire in the firepot. He kept doing so until the whole scroll was burned up in the fire.
36:24 Neither he nor any of his attendants showed any alarm when they heard all that had been read. Nor did they tear their clothes to show any grief or sorrow.
