13 For this reason I speak to them in figures, because, though they see, they do not see, and though they hear, they do not hear nor understand,

14 and to them is fulfilled the prophecy of Isaiah: 'You will plainly hear, but you will not understand, and you will clearly look, but you will not see.

15 For the heart of these people has grown fat, and with their ears they are dull of hearing and their eyes they have closed; so that they may not see with their eyes and hear with their ears and understand with their heart and repent and I should heal them.'
