2 Samuel 2:26

22Abner said again to Asahel, “Turn away from following me. Why should I strike you to the ground? How then could I look Joab your brother in the face?”

23However, he refused to turn away. Therefore Abner with the back end of the spear struck him in the body, so that the spear came out behind him; and he fell down there and died in the same place. As many as came to the place where Asahel fell down and died stood still.

24But Joab and Abishai pursued Abner. The sun went down when they had come to the hill of Ammah, that lies before Giah by the way of the wilderness of Gibeon.

25The children of Benjamin gathered themselves together after Abner and became one band, and stood on the top of a hill.

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.
