13 This is why I speak to them in parables:
“Though seeing, they do not see;
though hearing, they do not hear or understand.
14 In them is fulfilled the prophecy of Isaiah:
“‘You will be ever hearing but never understanding; 15 For this people’s heart has become calloused;
you will be ever seeing but never perceiving.
they hardly hear with their ears,
and they have closed their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts
and turn, and I would heal them.’
