Judges 15:14, 16

When he came to Lehi, the Philistines shouted as they met him. And the Spirit of the LORD came upon him mightily so that the ropes that were on his arms were as flax that is burned with fire, and his bonds dropped from his hands.

Then Samson said, “With the jawbone of a donkey, Heaps upon heaps, With the jawbone of a donkey I have killed a thousand men.”
