{In secret} (en krupt(9369)). See  Mt 6:4,6  for this phrase.
{Openly} (en parr(8873)i(8369)). "In public" (p(836e), r(8873)is, telling it
all). See on 烘t 8:32|. Common in John ( 7:13,26  10:24  16:25,29  18:20 ; here again contrasted with en krupt(9369)). It is
wise advice in the abstract that a public teacher must allow
inspection of his deeds, but the motive is evil. They might get
Jesus into trouble. If thou doest these things (ei tauta
poieis). This condition of the first class assumes the reality
of the deeds of Jesus, but the use of the condition at all throws
doubt on it all as in  Mt 4:3,6 . {Manifest thyself} (phaner(9373)on
seauton). First aorist active imperative of phanero(935c). {To the
world} (	(9369) kosm(9369)). Not just to "thy disciples," but to the
public at large as at the feast of tabernacles. See  8:26  14:22 
for this use of kosmos.
