2 Samuel 18:7-9

There Israel’s troops were routed by David’s men, and the casualties that day were great—twenty thousand men. The battle spread out over the whole countryside, and the forest swallowed up more men that day than the sword. Now Absalom happened to meet David’s men. He was riding his mule, and as the mule went under the thick branches of a large oak, Absalom’s hair got caught in the tree. He was left hanging in midair, while the mule he was riding kept on going.
