'Winnows' in the Bible

Now is not Boaz our kinsman, with whose maids you were? Behold, he winnows barley at the threshing floor tonight.

A [discerning] king who sits on the throne of judgmentSifts all evil [like chaff] with his eyes [and cannot be easily fooled].

A wise king winnows the wicked,And drives the threshing wheel over them.
