Judges 15:16 Meaning

15And he found a new jawbone of an ass, and put forth his hand, and took it, and slew a thousand men therewith.

16And Samson said, With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain a thousand men.

17And 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.

18And 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?
