Now ye are clean. — Better, Already are ye clean. The pronoun is emphatic. “Already are ye, as distinct from others who will become clean in the future.” (Comp. Note on John 13:10.)
Through the word which I have spoken unto you. — Better, on account of the word which I have spoken unto you. The word was the revelation of God to them, and by reason of its moral power they had been cleansed. We are not to limit the reference to John 13:10, but are to understand it of our Lord’s whole teaching. (See John 5:24; John 8:31-32; John 12:48; John 17:10; and comp. Note on Ephesians 5:26.)
