2 Samuel 18:14-17

14“Enough of this nonsense,” Joab said. Then he took three daggers and plunged them into Absalom’s heart as he dangled, still alive, in the great tree.

15Ten of Joab’s young armor bearers then surrounded Absalom and killed him.

16Then Joab blew the ram’s horn, and his men returned from chasing the army of Israel.

17They threw Absalom’s body into a deep pit in the forest and piled a great heap of stones over it. And all Israel fled to their homes.
