2 Samuel 18:16

Then Joab said, "I'm not going to wait like this with you." He took three darts in his hand, and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak.

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

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

Now Absalom in his lifetime had taken and reared up for himself the pillar, which is in the king's dale; for he said, "I have no son to keep my name in memory." He called the pillar after his own name; and it is called Absalom's monument, to this day.
