2 Samuel 18:14-17

14Joab replied, “I will not wait around like this for you!” He took three spears in his hand and thrust them into the middle of Absalom while he was still alive in the middle of the oak tree.

15Then ten soldiers who were Joab’s armor bearers struck Absalom and finished him off.

16Then Joab blew the trumpet and the army turned back from chasing Israel, for Joab had called for the army to halt.

17They took Absalom, threw him into a large pit in the forest, and stacked a huge pile of stones over him. In the meantime all the Israelite soldiers fled to their homes.
