13 Therefore, I speak to them in parables because seeing they see not, and hearing they hear not, neither do they understand.
14 And in them is fulfilled the prophecy of Isaiah, which says, By hearing ye shall hear and shall not understand, and seeing ye shall see and shall not perceive;
15 for this people's heart is waxed gross, and [their] ears are dull of hearing, and their eyes they have closed 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.
