²⁶ ‘Go to this people and say:
You will listen and listen, but you will not understand.
    You will look and look, but you will not learn,
²⁷ because these people have become stubborn.
    They don’t hear with their ears,
    and they have closed their eyes.
Otherwise, they might really understand
    what they see with their eyes
    and hear with their ears.
They might really understand in their minds
    and come back to me and be healed.’ Isaiah 6:9–10
