{Seasoned with salt} (halati (8872)tumenos). The same verb
artu(935c) (old verb from air(935c), to fit, to arrange) about salt in
 Mr 9:50  Lu 14:34 . Nowhere else in the N.T. Not too much salt,
not too little. Plutarch uses salt of speech, the wit which
flavours speech (cf. Attic salt). Our word salacious is this same
word degenerated into vulgarity. Grace and salt (wit, sense) make
an ideal combination. Every teacher will sympathize with Paul's
desire "that ye know how ye must answer each one" (eidenai p(9373)
dei humas heni ekast(9369) apokrinesthai). Who does know?
