2 Samuel 18:14-17

14Then said Joab, I may not tarry thus with thee. And he took three spears in his hand, and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak.12 15And ten young men that bore Joab’s armour surrounded and smote Absalom, and slew him. 16And Joab blew the trumpet, and the people returned from pursuing Israel: for Joab restrained the people. 17And they took Absalom, and cast him into a great pit in the forest, and laid a very great heap of stones upon him: and all Israel fled every one to his tent.
