2 Samuel 2:25-28

Abner’s troops from the tribe of Benjamin regrouped there at the top of the hill to take a stand. Abner shouted down to Joab, “Must we always be killing each other? Don’t you realize that bitterness is the only result? When will you call off your men from chasing their Israelite brothers?” Then Joab said, “God only knows what would have happened if you hadn’t spoken, for we would have chased you all night if necessary.” So Joab blew the ram’s horn, and his men stopped chasing the troops of Israel.
