Matthew 13:13–14

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.”

This is why I speak to them in parables:

“Though seeing, they do not see;

though hearing, they do not hear or understand.

In them is fulfilled the prophecy of Isaiah:

“ ‘You will be ever hearing but never understanding;

you will be ever seeing but never perceiving.

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 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.

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:
