Chaff

Chaff - (Easton's Bible Dictionary)

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).

Chaff - (Webster's 1828 Dictionary)

CHAFF, n.

1. The husk, or dry calyx of corn, and grasses. In common language, the word is applied to the husks when separated from the corn by thrashing, riddling or winnowing. The word is sometimes used rather improperly to denote straw cut small for the food of cattle.

2. Refuse; worthless matter; especially that which is light, and apt to be driven by the wind. In scripture, false doctrines, fruitless designs, hypocrites and ungodly men are compared to chaff. Psa 1:4; Jer 23:28; Isa 33:11; Mat 3:12.
