And Absalom met the servants of David. And Absalom rode upon a mule, and the mule went under the thick boughs of a great oak, and his head caught hold of the oak, and he was taken up between the heaven and the earth; and the mule that was under him went away.(2 Samuel 18:9)

And a certain man saw it, and told Joab, and said, Behold, I saw Absalom hanged in an oak.(2 Samuel 18:10)

And 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.(2 Samuel 18:11)

Otherwise 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.(2 Samuel 18:13)

Then 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.(2 Samuel 18:14)

And ten young men that bare Joab's armor compassed about and smote Absalom, and slew him.(2 Samuel 18:15)
