2 Samuel 18:14

10And a certain man saw it, and told Joab, and said, Behold, I saw Absalom hanged in an oak.

11And Joab said unto the man that told him, And, behold, thou sawest him, and why didst thou not smite him there to the ground? and I would have given thee ten shekels of silver, and a girdle.

12And the man said unto Joab, Though I should receive a thousand shekels of silver in mine hand, yet would I not put forth mine hand against the king’s son: for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom.

13Otherwise I should have wrought falsehood against mine own life: for there is no matter hid from the king, and thou thyself wouldest have set thyself against me.

14Then said Joab, I may not tarry thus with thee. And 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.

15And ten young men that bare Joab’s armour compassed about and smote Absalom, and slew him.

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

17And they took Absalom, and cast him into a great pit in the wood, and laid a very great heap of stones upon him: and all Israel fled every one to his tent.

18Now Absalom in his lifetime had taken and reared up for himself a pillar, which is in the king’s dale: for he said, I have no son to keep my name in remembrance: and he called the pillar after his own name: and it is called unto this day, Absalom’s place.
