'Jaw bone' in the Bible

He found a fresh jawbone of a donkey, so he reached out 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 donkeyI have killed a thousand men.”

When he had finished speaking, he threw the jawbone from his hand; and he named that place Ramath-lehi.
