'Winnow' in the Bible

You shall winnow them and [the] wind shall carry them, and [the] tempest shall scatter them. And you yourself shall rejoice in Yahweh; you shall boast in the holy one of Israel.

At that time it will be said to this people and to Jerusalem, "{A hot wind from the barren heights} in the desert, {in the direction of} the daughter of my people, not to winnow and not to cleanse,

And I will send winnowers to Babylon, and they will winnow her, and they will lay waste her land, for they will be against her from all sides on [the] day of disaster.
