Matthew 13:10-15

10And the disciples came and said to Him, “Why do You speak to them in parables?”

11He answered and said to them, “Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given.

12For whoever has, to him more will be given, and he will have abundance; but whoever does not have, even what he has will be taken away from him.

13Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand.

14And in them the prophecy of Isaiah is fulfilled, which says: ‘Hearing you will hear and shall not understand, And seeing you will see and not perceive;

15For the hearts of this people have grown dull. Their ears are hard of hearing, And their eyes they have closed, Lest they should see with their eyes and hear with their ears, Lest they should understand with their hearts and turn, So that I should heal them.’
