Judges 15:15-19

Then he found a fresh jawbone of a donkey, so he reached out with his hand and took it, and killed a thousand men with it.

And Samson said, “With the jawbone of a donkey, Heaps upon heaps, With the jawbone of a donkey I have killed a thousand men.”

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

Then he became very thirsty, and he called to the Lord and said, “You have handed this great victory over to Your servant, and now am I to die of thirst and fall into the hands of the uncircumcised?”

But God split the hollow place that is in Lehi so that water came out of it. When he drank, his strength returned and he revived. Therefore he named it En-hakkore, which is in Lehi to this day.
