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 (Ru 3:2; Isa 30:24; Jer 4:11-12; Mt 3:12).
