Judges 15:14 KJV

12And they said unto him, We are come down to bind thee, that we may deliver thee into the hand of the Philistines. And Samson said unto them, Swear unto me, that ye will not fall upon me yourselves.

13And they spake unto him, saying, No; but we will bind thee fast, and deliver thee into their hand: but surely we will not kill thee. And they bound him with two new cords, and brought him up from the rock.

14And 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.

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

16And Samson said, With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain a thousand men.
