And Joab blew the trumpet
 As the sign of a retreat: 
 and the people returned from pursuing after Israel;
 upon the sound of the trumpet, the meaning of which they understood: 
 for Joab held back the people:
 from shedding any more blood; the head of the conspiracy being removed, the thing would be crushed at once; and Joab neither chose to slay any more, nor take any prisoners, to be tried as traitors, being unawares, without thought, drawn into this rebellion.
