2 Samuel 2:26-28 Holman Christian Standard Bible (HCSB)
26 Then Abner called out to Joab: “Must the sword devour forever? Don’t you realize this will only end in bitterness? How long before you tell the troops to stop pursuing their brothers?”
27 “As God lives,” Joab replied, “if you had not spoken up, the troops wouldn’t have stopped pursuing their brothers until morning.” 28 Then Joab blew the ram’s horn, and all the troops stopped; they no longer pursued Israel or continued to fight.
