John Gill Commentary John 11:47

"The chief priests therefore and the Pharisees gathered a council, and said, What do we? for this man doeth many signs." — John 11:47 (ASV)

Then gathered the chief priests and the Pharisees a
council
They convened the sanhedrim, the great council of the nation together, of which they were some of the principal members:
