2 Samuel 18:9-10

And Absalom happened to meet the servants of David. 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, and he was suspended between heaven and earth, while the mule that was under him went on. And a certain man saw it and told Joab, “Behold, I saw Absalom hanging in an oak.”
