2 Samuel 2:28

26Then 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?”

27Joab said, “As God lives, if you had not spoken, surely then in the morning the people would have gone away, and not each followed his brother.”

28So Joab blew the trumpet; and all the people stood still and pursued Israel no more, and they fought no more.

29Abner and his men went all that night through the Arabah; and they passed over the Jordan, and went through all Bithron, and came to Mahanaim.

30Joab returned from following Abner; and when he had gathered all the people together, nineteen men of David’s and Asahel were missing.
