| 17. Linguistic Exegesis The verse opens with the aorist imperative hagiason {ἁγίασον | hagíason} ‘sanctify’, a direct plea from Jesus. The accusative plural autous {αὐτοὺς | autoús} identifies the disciples as the object. The preposition en with the dative te aletheíā {ἐν τῇ ἀληθείᾳ | en te alētheíā} specifies both the sphere and instrument of sanctification. The equative clause ho logos ho sós aletheía estin {ὁ λόγος ὁ σὸς ἀλήθεια ἐστιν | ho logos ho sós alētheía estin} employs the double article with the attributive pronoun sós to emphasize that the Father’s word is not merely a message but is itself truth, with the predicate nominative aletheia reinforcing identity. |
