Judges 15:17 (KJV)

And he found a new jawbone of an ass, and put forth his hand, and took it, and slew a thousand men therewith.

And Samson said, With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain 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 that place Ramath–lehi.

And he was sore athirst, and called on the Lord, and said, Thou hast given this great deliverance into the hand of thy servant: and now shall I die for thirst, and fall into the hand of the uncircumcised?

But God clave an hollow place that was in the jaw, and there came water thereout; and when he had drunk, his spirit came again, and he revived: wherefore he called the name thereof En–hakkore, which is in Lehi unto this day.
