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).
