'Jaw bone' in the Bible

He found a fresh jawbone of a donkey, reached out his hand, took it, and killed 1,000 men with it.

Then Samson said:With the jawbone of a donkeyI have piled them in a heap.With the jawbone of a donkeyI have killed 1,000 men.

When he finished speaking, he threw away the jawbone and named that place Ramath-lehi.
