{Manifestation} (phaner(9373)is). Late word, in papyri, in
N.T. only here and  2Co 4:2 , from phanero(935c), to make manifest
(phaneros). Each instance of the whole (verse  6 ) is
repeatedly given (didotai, present passive indicative of
did(936d)i). {To profit withal} (pros to sumpheron). See on
 6:12  10:23,33  for Paul's guiding principle in such matters.
