Judges 15:14-15

When he came unto Lehi, the Philistines shouted as they met him: and the Spirit of Jehovah came mightily upon him, and the ropes that were upon his arms became as flax that was burnt with fire, and his bands dropped from off his hands. And he found a fresh jawbone of an ass, and put forth his hand, and took it, and smote a thousand men therewith.
