Meaning
Chaff the refuse of winnowed corn. It was usually burned (Ex 15:7; Isa 5:24; Matt 3:12). This word sometimes, however, means dried grass or hay (Isa 5:24; 33:11). Chaff is used as a figure of abortive wickedness (Ps 1:4; Matt 3:12). False doctrines are also called chaff (Jer 23:28), or more correctly rendered "chopped straw." The destruction of the wicked, and their powerlessness, are likened to the carrying away of chaff by the wind (Isa 17:13; Hos 13:3; Zeph 2:2).
