Judges 15:13-17

13And they spoke to him, saying, No; but we will bind thee fast, and deliver thee into their hand; but we certainly shall not put thee to death. And they bound him with two new cords, and brought him up from the cliff.

14When he came to Lehi, the Philistines shouted against him. And the Spirit of Jehovah came upon him, and the cords that were on his arms became as threads of flax that are burned with fire, and his bands loosed from off his hands.

15And he found a fresh jawbone of an ass, and put forth his hand and took it, and slew with it a thousand men.

16And Samson said, With the jawbone of an ass, a heap, two heaps, With the jawbone of an ass have I slain a thousand men.

17And it came to pass when he had ended speaking, that he cast away the jawbone out of his hand, and called that place Ramath-Lehi.
