3 Bible Verses about Saws

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 sons of Ammon. So David and all the people returned unto Jerusalem.

All these works were of costly stones, cut and sawed with saws according to the measurements, within and without, even from the foundation unto the coping, and so on the outside unto the great court.

Shall the axe boast itself against him that hews with it? or shall the saw magnify itself against him that moves it? as if the rod should rise up against those that lift it up, or as if the staff should lift itself up. Is it not wood?
