And they come in to make sacrifices and burnt-offerings, and Jehu hath set for himself in an out-place eighty men, and saith, 'The man who letteth escape any of the men whom I am bringing in unto your hand -- his soul for his soul.'

And it cometh to pass, in that night, that a messenger of Jehovah goeth out, and smiteth in the camp of Asshur a hundred eighty and five thousand, and they rise early in the morning, and lo, all of them are dead corpses.
