2 Samuel 2:24-28

24When Joab and Abishai found out what had happened, they set out after Abner. The sun was just going down as they arrived at the hill of Ammah near Giah, along the road to the wilderness of Gibeon.

25Abner’s troops from the tribe of Benjamin regrouped there at the top of the hill to take a stand.

26Abner 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?”

27Then Joab said, “God only knows what would have happened if you hadn’t spoken, for we would have chased you all night if necessary.”

28So Joab blew the ram’s horn, and his men stopped chasing the troops of Israel.
