To CLEAN, and of a plant to PRUNE — the two are one act in Greek, which is the whole point of John 15:2-3. The verb is airō with a prefix; its adjective is katharos, 'clean', which is the next word in verse 3. ⚠ So verse 3 is not a change of subject but the punchline: he prunes-clean the fruitful branch, and you have already had that done to you. ⚠ On this shelf only the ASV keeps the link ('he CLEANSETH it... already ye are CLEAN'); KJV and Geneva say 'purgeth', NIV 'prunes'. Reina-Valera keeps it in Spanish with limpiará / limpios. → first discussed at John 15:2
