Judges 15:13-17

So they said to him, “No, we will [only] bind you securely and place you into their hands; but we certainly will not kill you.” So they bound him with two new ropes and brought him up from the rock [of Etam]. 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. He found a fresh jawbone of a donkey, so he reached out his hand and took it and killed a thousand men with it. 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.” When he finished speaking, he threw the jawbone from his hand; and he named that place Ramath-lehi (hill of the jawbone).
