Manifestation (phanerōsis). Late word, in papyri, in N.T. only here and 2Co 4:2, from phaneroō, to make manifest (phaneros). Each instance of the whole (1Co 12:6) is repeatedly given (didotai, present passive indicative of didōmi).
To profit withal (pros to sumpheron). See 1Co 6:12; 1Co 10:23, 1Co 10:33 for Paul’s guiding principle in such matters.
