John 18:27 — ExegesisTAB

The verse opens with palin {πάλιν | pá-lin} ‘again’, which marks repetition and links this denial to the earlier failures in the narrative. Oun {οὖν | oun} adds an inferential movement, so the statement reads as a narrative step forward rather than an isolated remark. The main verb ernēsato {ἠρνήσατο | ēr-né-sa-to} presents the denial as a complete past event, and Petros {Πέτρος | Pét-ros} follows after the verb in a normal Greek post-verbal position, keeping the focus first on the act and then on the actor. Kai {καὶ | kai} simply joins the next clause without softening the scene. Eutheos {εὐθέως | eu-thé-ōs} ‘immediately’ compresses the timeline, making the crowing follow the denial without delay. Alektor {ἀλέκτωρ | a-lék-tōr} stands as the subject of the second clause, and ephonesen {ἐφώνησεν | e-phṓ-nē-sen} closes the verse with the rooster’s cry as the narrative sign that Jesus’ prior warning has come to pass. The English rendering smooths the Greek order while preserving the abrupt sequence: repeated denial, then instantaneous crowing.
