'Saws' in the Bible

He brought forth the people who were therein, and put them under saws, and under iron picks, and under axes of iron, and made them pass through the brick kiln: and he did so to all the cities of the children of Ammon. David and all the people returned to Jerusalem.

All these were of costly stones, even of cut stone, according to measure, sawed with saws, inside and outside, even from the foundation to the coping, and so on the outside to the great court.

He brought forth the people who were therein, and cut [them] with saws, and with iron picks, and with axes. David did so to all the cities of the children of Ammon. David and all the people returned to Jerusalem.

Should an axe brag against him who chops with it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood.
