Judges 15:16-20

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.

And he judged Israel in the days of the Philistines twenty years.
