I believe that this picture represents Judas betraying Jesus as in the background you can see Judas talking to what i believe is a pharisee who is giving Judas 30 pieces of silver.
I believe that the apostles in the crowd are following Jesus because Jesus is in the middle.
I believe that the crowd are surprised by Jesus's powers.
I believe this is the garden scene as Jesus appears to be breaking up a fight which could represent
Peter cutting off a soldiers ear.
