João 9:13

They bring to the Pharisees him that aforetime was blind.

This event was before a gathering of the entire hierarchy: (1) because the neighbors' action presupposes an assembly in a stated place known in advance by them, and (2) because "they cast him out" (of the synagogue) indicates a formal and official meeting (John 9:34). That such a full-dress meeting of the Sanhedrin occurred was a testimony of the priority which the religious leaders gave to the problem of Jesus' growing power and influence among the people; and such an astounding miracle wrought under their very noses and supported by irrefutable evidence would have topped any agenda they might have had.
