δικαιόω

δικαίῳ; future δικαιώσω; 1 aorist ἐδικαίωσα; passive (present δικαιοῦμαι); perfect δεδικαίωμαι; 1 aorist ἐδικαιωθην; future δικαιωθήσομαι; (δίκαιος); the Sept. for צִדֵּק and הִצְדִּיק;
1. properly, (according to the analogy of other verbs ending in, as τυφλόω, δουλόω) to make δίκαιος; to render righteous or such as he ought to be; (Vulg.justifico); but this meaning is extremely rare, if not altogether doubtful; ἐδικαίωσα τήν καρδίαν μου stands for לְבָבִי זִכִּיתִי in Ps 72:13 (unless I have shown my heart to be upright be preferred as the rendering of the Greek there).
2. τινα, to show, exhibit, evince, one to be righteous, such as he is and wishes himself to be considered (Ezek 16:51f; τήν ψυχήν αὐτοῦ, Jer 3:11, and, probably, δικαιοῦν δίκαιον, Isa 53:11): ἡ σοφία ἐδικαιώθη ἀπό τῶν τέκνων αὐτῆς, the wisdom taught and exemplified by John the Baptist, and by Jesus, gained from its disciples (i. e. from their life, character, and deeds) the benefit of being shown to be righteous, i. e. true and divine (cf. Buttmann, 322 (277); others interpret, was acknowledged to be righteous on the part of (nearly, equivalent to, by) her children; cf. Buttmann, 325 (280); see ἀπό, II. 2 d. bb.), Lk 7:35; Mt 11:19 (here T Tr text WH read ἔργων, i. e. by her works); passive, of Christ: ἐδικαιώθη ἐν πνεύματι, evinced to be righteous as to his spiritual (divine ((?) cf. e. g. Ellicott at the passage or Meyer on Rom 1:4)) nature, 1 Tim 3:16; of God: ὅπως δικαιωθῇς ἐν τοῖς λόγοις σου, Rom 3:4 from Ps 50:6 (κύριος μόνος δικαιωθήσεται, Sir. 18:2); passive used reflexively, to show oneself righteous: of men, Rev 22:11 Rec.; (τί δικαιωθῶμεν; Gen 44:16).
3. τινα, to declare, pronounce, one to be just, righteous, or such as he ought to be, (cf. ὁμοιόω to declare to be like, liken, i. e. compare; ὁσιόω, Wis. 6:11; ἀξιόω, which never means to make worthy, but to judge worthy, to declare worthy, to treat as worthy; see also κοινόω, 2 b.);
a. with the negative idea predominant, to declare guiltless one accused or who may be accused, acquitted of a charge or reproach, (Deut 25:1; Sir. 13:22 (21), etc.; an unjust judge is said δικαιοῦν τόν ἀσεβῆ in Ex 23:7; Isa 5:23): ἑαυτόν, Lk 10:29; passive οὐ δεδικαίωμαι, namely, with God, 1 Cor 4:4; pregnantly with ἀπό τῶν ἁμαρτιῶν added, to be declared innocent and therefore to be absolved from the charge of sins (cf. Buttmann, 322 (277)), Acts 13:38 (39) (so ἀπό ἁμαρτίας, Sir. 26:29; simply, to be absolved, namely, from the payment of a vow, Sir. 18:22 (21)); hence, figuratively, by a usage not met with elsewhere, to be freed, ἀπό τῆς ἁμαρτίας, from its dominion, Rom 6:7, where cf. Fritzsche or ((less fully) Meyer).
b. with the positive idea predominant, to judge, declare, pronounce, righteous and therefore acceptable, (God is said δικαιοῦν δίκαιον, 1 Kgs 8:32): ἑαυτόν, Lk 16:15; ἐδικαίωσαν τόν Θεόν, declared God to be righteous, i. e. by receiving the baptism declared that it had been prescribed by God rightly, Lk 7:29; passive by God, Rom 2:13; ἐξ ἔργων ἐδικαιώθη, got his reputation for righteousness (namely, with his countrymen (but see Meyer (edited by Weiss) at the passage)) by works, Rom 4:2; ἐκ τῶν λόγων, by thy words, in contrast with καταδικάζεσθαι, namely, by God, Mt 12:37. Especially is it so used, in the technical phraseology of Paul, respecting God who judges and declares such men as put faith in Christ to be righteous and acceptable to him, and accordingly fit to receive the pardon of their sins and eternal life (see δικαιοσύνη, 1 c.): thus absolutely, δικαιοῦν τινα, Rom 3:26; Rom 4:5; Rom 8:30, Rom 8:33 (namely, ἡμᾶς, opposed to ἐγκάλειν); with the addition of ἐκ (in consequence of) πίστεως, Rom 3:30; Gal 3:8; of διά τῆς πίστεως, Rom 3:30; men are said δικαιοῦσθαι, δικαιωθῆναι, τῇ χάριτι τοῦ Θεοῦ, Tit 3:7; δωρεάν τῇ χάριτι τοῦ Θεοῦ, Rom 3:24 πίστει, Rom 3:28; ἐκ πίστεως, by means of faith, Rom 5:1; Gal 2:16; Gal 3:24; ἐν τῷ αἵματι τοῦ Χριστοῦ (as the meritorious cause of their acceptance, as the old theologians say, faith being the apprehending or subjective cause), Rom 5:9; ἐν τῷ ὀνόματι τοῦ κυρίου Ἰησοῦ καί ἐν τῷ πνεύματι τοῦ Θεοῦ ἡμῶν, by confessing the name of the Lord (which implies faith in him, Rom 10:10, cf. 2 Cor 4:13), and by the Spirit of God (which has awakened faith in the soul), 1 Cor 6:11; ἐν Χριστῷ through Christ, Gal 2:17; Acts 13:39; it is vehemently denied by Paul, that a man δικαιοῦται ἐξ ἔργων νόμου, Gal 2:16 — with the addition ἐνώπιον αὐτοῦ, i. e. of God, Rom 3:20, cf. Rom 3:28; Rom 4:2, (see δικαιοσύνην, 1 c. under the end) — a statement which is affirmed by James in Jas 2:21, f (though he says simply ἐξ ἔργων δικαιοῦται, significantly omitting νόμου); to the same purport Paul denies that a man δικαιοῦται ἐν νόμῳ, in obeying the law, or by keeping it, Gal 5:4; with the addition, παρά τῷ Θεῷ, in the sight of God, Gal 3:11. Lk 18:14 teaches that a man δικαιοῦται by deep sorrow for his sins, which so humbles him that he hopes for salvation only from divine grace. The Pauline conceptions of δίκαιος, δικαιοσύνη, δικαιόω, are elucidated especially by Winzer, De vocabulis δίκαιος, etc., in Ep. ad Rom., Lipsius 1831; Usteri, Paulin.

On the patristic usage see Reithmayr, Galaterbrief, p. 177f; Cremer, Worterbuch, 4te Aufl., p. 285; Suicer, Thesaurus under the word). In classic Greek δικαιόω (Ionic δικαιέω, Herodotus) is:
1. equivalent to δίκαιον νομίζω, to deem right or fair: τί, often followed by the infinitive; to choose what is right and fair, hence, universally, to choose, desire, decide: Herodotus, Sophocles, Thucydides, others.
2. with the accusative of person, τό δίκαιον ποιῶ τινα to do one justice, in a bad sense, viz. to condemn, punish, one: Herodotus, Thucydides, Plato, others; hence, δικαιοῦσθαι, to have justice done oneself, to suffer justice, be treated rightly, opposed to ἀδικεῖσθαι, Aristotle, eth. Nic. 5, 9, 11, p. 1136{a}, 18ff (In like manner the German rechtfertigen in its early forensic use bore a bad sense, viz. to try judicially (so for ἀνακρίνειν, Acts 12:19 Luther), then condemn; execute judgment, especially put to death.)
