2 Samuel 18:9-14

Now Absalom met the servants of David. Absalom was riding on his mule, and the mule went under the thick branches of a massive tree, and his head was caught in [the thick branches of] the tree; and he was left hanging [in midair] between heaven and earth, while the mule that had been under him kept going. A certain man saw it and informed Joab, saying, “I saw Absalom hanging in a tree.” Joab said to the man who informed him, “You saw him! Why then did you not strike him there to the ground? I would have given you ten pieces of silver and a belt.” The man told Joab, “Even if I were to feel the weight of a thousand pieces of silver in my hands, I would not put out my hand against the king’s son; for we all heard the king command you, Abishai, and Ittai, saying, ‘Protect the young man Absalom, for my sake.’ Otherwise, if I had acted treacherously against his life (for nothing is hidden from the king) you yourself would have taken sides against me.” Joab said, “I will not waste time with you.” So he took three spears in his hand and thrust them through the heart of Absalom while he was still alive [and caught] in the midst of the tree.
