1. properly, to show, i. e. expose to the eyes: τίνι τί, Mt 4:8; Lk 4:5; Lk 20:24 (for Rec. ἐπιδείξατέ); Lk 22:12; (R G L, but T omits; Tr brackets WH reject the verse); Mk 14:15; Jn 20:20; Acts 7:3; ὁδόν τίνι, metaphorically, in which one ought to go, i. e. to teach one what he ought to do, 1 Cor 12:31; κατά τόν τύπον τόν δειχθέντα σοι, Heb 8:5; ἑαυτόν δεικνύναι τίνι to expose oneself to the view of one, Mt 8:4; Mk 1:44; Lk 5:14; δεῖξον ἡμῖν τόν πατέρα render the Father visible to us, Jn 14:8f; of things presented to one in a vision: τίνι τί, Rev 17:1; Rev 21:9; Rev 22:1, Rev 22:8; δεῖξαι τίνι, ἅ δεῖ γενέσθαι, Rev 1:1; Rev 4:1; Rev 22:6. to show, equivalent to to bring to pass, produce what can be seen (German sehenlassen); of miracles performed in presence of others to be seen by them: σημεῖον, Jn 2:18, (Baruch 6 (i. e., epistle of Jeremiah) 66; σῆμα, Homer, Odyssey 3, 174; Iliad 13, 244); ἔργα ἐκ τίνος, works done by the aid of one, Jn 10:32; τήν ἐπιφάνειαν Ἰησοῦ Χριστοῦ, spoken of God, as the author of Christ's visible return, 1 Tim 6:15; ἔργα δεικνύειν is used differently in Jn 5:20, to show works to one for him to do.
2. metaphorically,
a. with the accusative of the thing, to give the evidence or proof of a thing: πίστιν, Jas 2:18; τί ἐκ τίνος, as τήν πίστιν ἐκ τῶν ἔργων, ibid.; τά ἔργα ἐκ τῆς καλῆς ἀναστροφῆς, Jas 3:13.
b. to show by words, to teach: followed by ὅτι, Mt 16:21 (διδάσκειν in Mk 8:31 for δεικνύειν); followed by an infinitive Acts 10:28. (Compare: ἀναδείκνυμι, ἀποδείκνυμι, ἐνδείκνυμι, ἐπιδείκνυμι, ὑποδείκνυμι.)
