'Winnowing' in the Bible

“I will winnow them with a winnowing forkAt the gates of the land;I will bereave them of children, I will destroy My people;They did not repent of their ways.

His winnowing fork is in His hand, and He will thoroughly clear His threshing floor; and He will gather His wheat into the barn, but He will burn up the chaff with unquenchable fire.”
