2 Samuel 18:14-17

14Joab said, “I will not waste time with you.” So he took three spears in his hand and thrust them through the heart of Absalom while he was still alive [and caught] in the midst of the tree.

15And ten young men, Joab’s armor bearers, surrounded and struck Absalom and killed him.

16Then Joab blew the trumpet [to signal the end of the combat], and the men returned from pursuing Israel, for Joab held them back.

17They took [down the body of] Absalom and threw him into a deep pit in the forest and set up a huge mound of stones over him. Then all Israel fled, everyone to his own tent.
