'Winnowed' in the Bible

O my threshed people [Judah, who must be judged and trampled down by Babylon], my afflicted of the threshing floor.What I have heard from the Lord of hosts,The God of Israel, I have [joyfully] announced to you [that Babylon is to fall].

Also the oxen and the young donkeys that work the ground will eat salted fodder, which has been winnowed with shovel and pitchfork.
