2 Samuel 18:15

The man said to Joab, “Though I should receive a thousand pieces of silver in my hand, I still wouldn’t stretch out my hand against the king’s son; for in our hearing the king commanded you and Abishai and Ittai, saying, ‘Beware that no one touch the young man Absalom.’

Otherwise, if I had dealt falsely against his life (and there is no matter hidden from the king), then you yourself would have set yourself against me.”

Then 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.

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

They 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.

Now 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.
