Matthew 13:13

13 For this cause I speak to them in parables, because seeing they do not see, and hearing they do not hear nor understand;

Matthew 13:13 In-Context

11 And he answering said to them, Because to you it is given to know the mysteries of the kingdom of the heavens, but to them it is not given;
12 for whoever has, to him shall be given, and he shall be caused to be in abundance; but he who has not, even what he has shall be taken away from him.
13 For this cause I speak to them in parables, because seeing they do not see, and hearing they do not hear nor understand;
14 and in them is filled up the prophecy of Esaias, which says, Hearing ye shall hear and shall not understand, and beholding ye shall behold and not see;
15 for the heart of this people has grown fat, and they have heard heavily with their ears, and they have closed their eyes as asleep, lest they should see with the eyes, and hear with the ears, and understand with the heart, and should be converted, and I should heal them.
