Moth

Heb. 'ash, from a root meaning "to fall away," as moth-eaten
garments fall to pieces (Job 4:19; 13:28; Isa. 50:9; 51:8; Hos.
5:12).

Gr. ses, thus rendered in Matt. 6:19, 20; Luke 12:33. Allusion
is thus made to the destruction of clothing by the larvae of the
clothes-moth. This is the only lepidopterous insect referred to
in Scripture.
