John 5:37 NEITHER SEEN NOR HEARD

John 5:37

And the Father Who sent Me has Himself testified concerning Me. Not ONE of YOU has ever given ear to His voice or seen His form (His face—what He is like). [You have always been deaf to His voice and blind to the vision of Him.] What did the crowd of Greeks hear Jn. 12:20 hear described in John 12:29? so these specific leaders were not present here NOR at his baptism? Luke 3:22 Mark 1:11

Read Matt 3:4,5,6,7  when were the Pharisees and Sadducees said to be there?  Did they hear the voice?
