2 Samuel 18:9-10

Then Absalom [unavoidably] met the servants of David. Absalom rode on a mule, and the mule went under the thick boughs of a great oak, and Absalom's head caught fast [in a fork] of the oak; and the mule under him ran away, leaving him hanging between the heavens and the earth. A certain man saw it and told Joab, Behold, I saw Absalom hanging in an oak.
