2 Samuel 2:26-28 World English Bible (WEB)
26 Then Abner called to Joab, and said, “Shall the sword devour forever? Don’t you know that it will be bitterness in the latter end? How long will it be then, before you ask the people to return from following their brothers?”
27 Joab said, “As God[a] lives, if you had not spoken, surely then in the morning the people would have gone away, and not each followed his brother.” 28 So Joab blew the trumpet; and all the people stood still, and pursued Israel no more, and they fought no more.
