43 Throughout the translation John’s use of καί (kai) often reflects the varied usage of the Hebrew conjunction ו (vav). A clause which καί introduces has been translated in terms of its semantic relationship to the clause that preceded it. If the καί seemed redundant, however, it was left untranslated; that is the case in this verse.
44 Grk “with me.” The translation “with me” implies that John was engaged in a dialogue with the one speaking to him (e.g., Jesus or an angel) when in reality it was a one-sided conversation, with John doing all the listening. For this reason, μετʼ ἐμοῦ (met’ emou, “with me”) was translated as “to me.”
45 Grk “and turning I saw.” The repetition of ἐπιστρέφω (epistrephō) is somewhat redundant in contemporary English and has been translated generally.
