The ninth nave window

This window reminds us of the thirty pieces of silver which Judas Iscariot was paid for betraying Jesus to the Jewish authorities –
“Then one of the twelve, whose name was Judas Iscariot, went to the chief priests and said, ‘What will you give me if I deliver him over to you?’ And they paid him thirty pieces of silver. And from that moment he sought an opportunity to betray him.
