Matthew 13:10-15

10Then the disciples came to Him and said, “Why do You speak to them in parables?”

11And He replied to them, “To you has been given to know the secrets of the kingdom of heaven, but to them it has not been given.

12For whoever has, to him more will be given and he will have plenty. But whoever does not have, even what he has will be taken away from him.

13For this reason 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 being fulfilled, which says, ‘You will keep on hearing but will never understand; you will keep looking, but will never see.

15For the heart of this people has become dull, their ears can barely hear, and they have shut their eyes. Otherwise they might see with their eyes, hear with their ears, and understand with their hearts. Then they would turn back, and I would heal them.’
