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

14 And in them the prophecy of Isaiah is fulfilled, which says: Hearing you will hear and shall not at all understand, and seeing you will see and by no means perceive;

15 for the heart of this people has grown dull, their ears are hard of hearing, and their eyes they have closed, that they should not see with their eyes, nor hear with their ears, nor understand with their heart and convert, and I should heal them.
