2 Samuel 2:26-28 Amplified Bible, Classic Edition (AMPC)
26 Then Abner called to Joab, Shall the sword devour forever? Do you not know that bitterness will be the result? How long will it be then before you bid the people to stop pursuing their brethren?
27 Joab said, As God lives, if you had not spoken, surely the men would have stopped pursuing their brethren in the morning.
28 So Joab blew a trumpet, and all the people stood still and pursued Israel no more, nor did they fight any more.
