Acts 18:28ExegesisTAB

Acts 18 : 28 Refutation | Scripture | Messiah
28. Linguistic Exegesis
The adverb eutonos {εὐτόνως | eu-tó-nōs} is placed at the beginning for emphasis on the manner of refutation. The postpositive conjunction gar {γὰρ | gar} links this statement to the preceding narrative, offering an explanatory “for.” The dative phrase tois Ioudaiois {τοῖς Ἰουδαίοις | tois I-ou-daí-ois} marks the Jewish audience as recipients and opponents of the refutation. The imperfect middle indicative diakatelenkheto {διακατηλέγχετο | di-a-ka-te-léng-khe-to} conveys repeated, vigorous argumentation rather than a single instance. The adverb dēmosia {δημοσίᾳ | dē-mo-sí-āi} highlights that this engagement occurred openly. The participle epideiknys {ἐπιδεικνὺς | e-pi-deí-k-nys} functions as a modal participle describing the means of refutation—“demonstrating.” The prepositional phrase dia tōn graphōn {διὰ τῶν γραφῶν | di-a tōn gra-phōn} uses dia with the genitive to denote the Scriptures as the instrument and authority of his proof. The infinitive clause einai ton christon Iēsoun {εἶναι τὸν χριστὸν Ἰησοῦν | eî-nai ton khris-tón Iē-soûn} is an accusative-infinitive construction dependent on epideiknys, stating the content of the demonstration: that Jesus is the Christ. In English this is rendered with a finite clause “proving that Jesus is the Christ” to preserve clarity and emphasis on the scriptural basis.
