UBS Dictionary of the Greek New Testament
verb | fut. ὑποδείξω · aor. ὑπέδειξα | δείκνυμι
28.47 · Know · Well Known, Clearly Shown, Revealed
to make known, to demonstrate, to show to make known the character or significance of something by visual, auditory, gestural, or linguistic means In some languages it may be useful to translate ὑποδείκνυμι in ACT 20:35 as ‘I showed you by example’ or ‘I demonstrated by example’ or ‘I showed you by what I did.’
1 It is possible that ὑποδείκνυμι[a] is somewhat more emphatic or intensive in connotation than δείκνυμι[a], but this cannot be shown from existing contexts. 2 There may very well be a slight difference of meaning between δείκνυμι[b] and ὑποδείκνυμι[b], but this cannot be determined from existing contexts.
