“They said to him.
‘What did he do
How did he open
εἶπαν οὖν αὐτῷ Τί ἐποίησέν σοι; πῶς ἤνοιξέν σου τοὺς ὀφθαλμούς;
John uniquely indicated that these Jewish people asked him (εἶπαν οὖν αὐτῷ) what Jesus had done to him (Τί ἐποίησέν σοι). How had he opened his eyes (πῶς ἤνοιξέν σου τοὺς ὀφθαλμούς)? This Jewish group or Pharisees wanted to know exactly what did Jesus do to open his eyes. How did he get his sight back? What procedure did he use to get him to see again? How did Jesus help you not to be blind?
