2 Samuel 12:31; 2 Samuel 23:7

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.

7 But the man that shall touch them must be fenced with iron and the staff of a spear; and they shall be utterly burned with fire in the same place.
