'Instrument' in the Bible

For the fitches are not threshed with a sharp threshing instrument, neither is a cart wheel turned about upon the cummin; but the fitches are beaten out with a staff, and the cummin with a rod.

Behold, I have made thee to be a new sharp threshing instrument having teeth; thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.
