2 Samuel 2:24

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?”
