the refuse of winnowed corn. It was usually burned (Ex. 15:7;
Isa. 5:24; Matt. 3:12). This word sometimes, however, means

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).
