'Instruments' in the Bible

How are the mighty fallen, and the instruments of war perished!

And David and all the house of Israel played before the LORD on all manner of instruments made of fir wood, even on harps, and on psalteries, and on timbrels, and on cornets, and on cymbals.

and the people who are in it he hath brought out, and setteth to the saw, and to cutting instruments of iron, and to axes of iron, and hath caused them to pass over into the brick-kiln; and so he doth to all the cities of the Bene-Ammon; and David turneth back, and all the people, to Jerusalem.

And Araunah said unto David, Let my lord the king take and offer up what seemeth good unto him: behold, here be oxen for burnt sacrifice, and threshing instruments and other instruments of the oxen for wood.
