2 Samuel 2:24-28

24But Joab and Abishai pursued Abner, and when the sun was going down, they came to the hill of Ammah, which is in front of Giah by the way of the wilderness of Gibeon.

25The sons of Benjamin gathered together behind Abner and became one band, and they stood on the top of a certain hill.

26Then Abner called to Joab and said, “Shall the sword devour forever? Do you not know that it will be bitter in the end? How long will you 1refrain from telling the people to turn back from following their brothers?”

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

28So Joab blew the trumpet; and all the people halted and pursued Israel no longer, 2nor did they continue to fight anymore.
