14 And in them is fulfilled the prophecy of Isaiah which said, By hearing you shall hear and shall not understand; and seeing you shall see and shall not perceive;

15 for this people's heart has become gross, and [their] ears are dull of hearing, and they have closed their eyes, 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.
