So in their case this prophecy of Isaiah is being fulfilled:
You will listen and listen again, but not understand,
see and see again, but not perceive.
For the heart of this nation has grown coarse,
their ears are dull of hearing, and they have shut their eyes,
for fear they should see with their eyes,
hear with their ears,
understand with their heart,
and be converted
and be healed by me.
‘But happy are your eyes because they see, your ears because they hear! I tell you solemnly, many prophets and holy men longed to see what you see, and never saw it; to hear what you hear, and never heard it.‘
