Judges 15:14-16

And when he came unto Lehi, the Philistines shouted against him: and the Spirit of the LORD came mightily upon him, and the cords that were upon his arms became as flax that was burnt with fire, and his bands loosed from off his hands. And he found a new jawbone of an ass, and put forth his hand, and took it, and slew a thousand men therewith. And Samson said, With the jawbone of an ass, heaps upon heaps, With the jaw of an ass have I slain a thousand men.
