New International Version
13 This is why I speak to them in parables:
“Though seeing, they do not see;
though hearing, they do not hear or understand.(A)
14 In them is fulfilled(B) the prophecy of Isaiah:
“‘You will be ever hearing but never understanding;
you will be ever seeing but never perceiving.
15 For this people’s heart has become calloused;
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.’[a](C)
- Matthew 13:15 Isaiah 6:9,10 (see Septuagint)
