Matthew 13:13–15

This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. Indeed, in their case the prophecy of Isaiah is fulfilled that says:

“ ‘ “You will indeed hear but never understand,

and you will indeed see but never perceive.”

For this people’s heart has grown dull,

and with their ears they can barely hear,

and their eyes they have closed,

lest they should see with their eyes

and hear with their ears

and understand with their heart

and turn, and I would heal them.’

That is why I speak to them in parables, because looking they do not see, and hearing they do not listen or understand. Isaiah’s prophecy is fulfilled in them, which says:

You will listen and listen,

but never understand;

you will look and look,

but never perceive.

For this people’s heart has grown callous;

their ears are hard of hearing,

and they have shut their eyes;

otherwise they might see with their eyes,

and hear with their ears, and

understand with their hearts,

and turn back—

and I would heal them.

That is why I use these parables,

For they look, but they don’t really see.

They hear, but they don’t really listen or understand.

This fulfills the prophecy of Isaiah that says,

‘When you hear what I say,

you will not understand.

When you see what I do,

you will not comprehend.

For the hearts of these people are hardened,

and their ears cannot hear,

and they have closed their eyes—

so their eyes cannot see,

and their ears cannot hear,

and their hearts cannot understand,

and they cannot turn to me

and let me heal them.’

For this reason I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand, and with reference to them the prophecy of Isaiah is fulfilled that says,

“You will listen carefully and will never understand,

and you will look closely and will never perceive.

For the heart of this people has become dull,

and with their ears they hear with difficulty,

and they have shut their eyes,

so that they would not see with their eyes

and hear with their ears

and understand with their heart

and turn, and I would heal them.”

Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive: For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
