'Thresh' in the Bible

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.

Arise and thresh, O daughter of Zion; for I will make thy horn iron, and I will make thy hoofs brass; and thou shalt beat in pieces many peoples: and I will devote their gain unto Jehovah, and their substance unto the Lord of the whole earth.

Thou didst march though the land in indignation; Thou didst thresh the nations in anger.

or saith he it assuredly for our sake? Yea, for our sake it was written: because he that ploweth ought to plow in hope, and he that thresheth, to thresh in hope of partaking.
