Judges 15:14, 16

When he came to Lehi, the Philistines came shouting to meet him. And the Spirit of the LORD came upon him mightily, and the ropes on his arms were like flax (linen) that had been burned, and his bonds dropped off his hands.

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