2 Samuel 2:24-28

24And Joab and Abishai pursued after Abner; and the sun went down when they came to the hill of Ammah, which is before Giah on the way to the wilderness of Gibeon.

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

26And Abner called to Joab, and said, Shall the sword devour for ever? knowest thou not that it will be bitterness in the latter end? and how long shall it be ere thou bid the people return from following their brethren?

27And Joab said, [As] 1God liveth, unless thou hadst spoken, surely then in the morning the people had gone up every one from following his brother.

28And Joab blew the trumpet, and all the people stood still, and pursued after Israel no more, neither did they fight any more.
