Ammon Scripture - 2 Samuel 12:31

And he brought forth the people that [were] therein, and put [them] under saws, and under harrows of iron, and under axes of iron, and made them pass through the brickkiln: and thus did he unto all the cities of the children of Ammon. So David and all the people returned unto Jerusalem.
