Passage
The Jews answered and said unto him, Say we not well that thou art a Samaritan, and hast a demon?
The Jews answered and said unto him, Say we not well that thou art a Samaritan, and hast a demon?
John 8:46 Which of you convicteth me of sin? If I say truth, why do ye not believe me?
John 8:47 He that is of God heareth the words of God: for this cause ye hear [them] not, because ye are not of God.
John 8:48 The Jews answered and said unto him, Say we not well that thou art a Samaritan, and hast a demon?
John 8:49 Jesus answered, I have not a demon; but I honor my Father, and ye dishonor me.
John 8:50 But I seek not mine own glory: there is one that seeketh and judgeth.
The verse centers on "jews", "answered", "said", "well", "thou", "samaritan", "hast", and "demon". It is saying that the verse draws attention to "jews" and "answered", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 47's "He that is of God heareth the..." into verse 49's "Jesus answered I have not a demon...", so "jews" and "answered" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "jews" and "answered" with trust shaped by these words, not by a vague optimism outside the passage.
