'Jaw bone' in the Bible

Then found he the jawbone of an ass newly-slain, - so he thrust forth his hand, and took it, and smote therewith, a thousand men.

And Samson said, With the jawbone of an ass, - have I piled them up in heaps! With the jawbone of an ass, have I smitten a thousand men!

And it came to pass, when he had made an end of speaking, that he cast away the jawbone out of his hand, - and called the name of that place, Ramath-lehi.
