2 Samuel 18:16

14Then Joab said, “I’m not going to wait like this with you.” He took three darts in his hand and thrust them through Absalom’s heart while he was still alive in the middle of the oak.

15Ten young men who bore Joab’s armor surrounded and struck Absalom, and killed him.

16Joab blew the trumpet, and the people returned from pursuing after Israel; for Joab held the people back.

17They took Absalom and cast him into a great pit in the forest, and raised over him a very great heap of stones. Then all Israel fled, each to his own tent.

18Now Absalom in his lifetime had taken and reared up for himself the pillar which is in the king’s valley, for he said, “I have no son to keep my name in memory.” He called the pillar after his own name. It is called Absalom’s monument, to this day.
