2 Samuel 18:9-12

Now Absalom happened to meet the servants of David. For Absalom was riding on his mule, and the mule went under the thick branches of a great oak. And his head caught fast in the oak, so he was left hanging between heaven and earth, while the mule that was under him kept going. When a certain man saw it, he told Joab and said, “Behold, I saw Absalom hanging in an oak.” Then Joab said to the man who had told him, “Now behold, you saw him! Why then did you not strike him there to the ground? And I would have given you ten pieces of silver and a belt.” The man said to Joab, “Even if I should receive a thousand pieces of silver in my hand, I would not put out my hand against the king’s son; for in our hearing the king charged you and Abishai and Ittai, saying, ‘Protect for me the young man Absalom!’
