13 This is why I speak to them in parables:
‘Though seeing, they do not see;
though hearing, they do not hear or understand.’13:13 See Deuteronomy 29:4, Isaiah 42:20, Jeremiah 5:21, and Ezekiel 12:2.
14 In them the prophecy of Isaiah is fulfilled:
‘You will be ever hearing but never understanding;
you will be ever seeing but never perceiving.
15 For this people’s heart has grown callous;
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.’13:15 Isaiah 6:9–10 (see also LXX)
