{Every idle word} (pan rh(886d)a argon). An ineffective,
useless word (a privative and ergon). A word that does no
good and so is pernicious like pernicious anaemia. It is a solemn
thought. Jesus who knows our very thoughts ( 12:25 ) insists that
our words reveal our thoughts and form a just basis for the
interpretation of character ( 12:37 ). Here we have judgment by
words as in  25:31-46  where Jesus presents judgment by deeds.
Both are real tests of actual character. Homer spoke of "winged
words" (pteroenta epea). And by the radio our words can be
heard all round the earth. Who knows where they stop?
