2 Samuel 18:9-10

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