Judges 15:14-15

When he came to Lehi, the Philistines came shouting to meet him. Then the Spirit of the LORD rushed upon him, and the ropes that were on his arms became as flax that has caught fire, and his bonds melted off his hands. And he found a fresh jawbone of a donkey, and put out his hand and took it, and with it he struck 1,000 men.
