2 Samuel 18:9-10

During the battle, Absalom was riding on his mule and he met some of David's soldiers. His mule carried him under a big oak tree. The tree's branches caught Absalom's hair so that he hung there above the ground. His mule ran off and left him there. One of David's men saw what had happened. He told Joab, ‘I have seen Absalom. He is hanging from an oak tree.’
