'Winnow' in the Bible

Thou shalt winnow them, and the wind shall carry them away, and the whirlwind shall scatter them; and thou shalt rejoice in Jehovah, thou shalt glory in the Holy One of Israel.

At that time shall it be said to this people and to Jerusalem, A hot wind from the bare heights in the wilderness toward the daughter of my people, not to winnow, nor to cleanse;

And I will send unto Babylon strangers, that shall winnow her; and they shall empty her land: for in the day of trouble they shall be against her round about.
