Then they went in to make offerings and burned offerings. Now Jehu had put eighty men outside, and said to them, If any man whom I give into your hands gets away, the life of him who lets him go will be the price of his life.

And that night the angel of the Lord went out and put to death in the army of the Assyrians a hundred and eighty-five thousand men; and when the people got up early in the morning, there was nothing to be seen but dead bodies.
