2 Samuel 18:9-10

Absalom came upon some of David’s men. Absalom was riding on a mule, and the mule went under the tangled branches of a large oak tree. Absalom’s head got caught in the tree. He was left hanging in midair while the mule under him kept on going. One of the men saw this and reported to Joab, “I just saw Absalom hanging from an oak tree.”
