2 Samuel 12:31

And he brought out the spoils of the city in great abundance, and he brought out the people who were in it, and put them to the saw, and to iron crows, and to pick axes of iron, and distributed them through brick yards. And when he had done the same to all the cities of the Ammonites, David, and all the people, returned to Jerusalem.

And he brought forth the people that were in it, and put them under the saw, and under iron harrows, and axes of iron, and made them pass through the brick-kiln: and thus he did to all the cities of the children of Ammon. And David and all the people returned to Jerusalem.
