Winnow
Corn was winnowed, (1.) By being thrown up by a shovel against
the wind. As a rule this was done in the evening or during the
night, when the west wind from the sea was blowing, which was a
moderate breeze and fitted for the purpose. The north wind was
too strong, and the east wind came in gusts. (2.) By the use of
a fan or van, by which the chaff was blown away (Ruth 3:2; Isa.
30:24; Jer. 4:11, 12; Matt. 3:12).
