A common misinterpretation of this verse is to view the Pharisees' questions as sincere curiosity or a model for rigorous inquiry into spiritual matters, ignoring the context of their hostile motive to discredit Jesus and trap the healed man, as seen in surrounding verses; another error is applying it isolated from the chapter to justify modern skepticism toward miracles without recognizing it as an example of willful rejection of God's evident work, or assuming the man's responses prove endless questioning leads to truth rather than exposing hardened hearts.
John 9:26
King James Version (1769)
26 Then said they to him again, What did he to thee? how opened he thine eyes?
In John 9:26, the Pharisees continue their intense interrogation of the man born blind whom Jesus healed, repeatedly demanding specifics on 'what did he to thee? how opened he thine eyes?', underscoring their spiritual obstinacy and refusal to acknowledge Jesus' divine power despite irrefutable evidence of the miracle, which contrasts sharply with the man's simple faith and highlights the theme of unbelief blinding those who should see the truth.
