Mattithyahu (Matthew) 13:10-15

And the taught ones came and said to Him, “Why do You speak to them in parables?” And He answering, said to them, “Because it has been given to you to know the secrets of the reign of the heavens, but to them it has not been given. “For whoever possesses, to him more shall be given, and he shall have overflowingly; but whoever does not possess, even what he possesses shall be taken away from him. “Because of this I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. “And in them the prophecy of Yeshayahu is completely filled, which says, ‘Hearing you shall hear and by no means understand, and seeing you shall see and by no means perceive, for the heart of this people has become thickened, and their ears are hard of hearing, and their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their heart, and turn back, and I heal them.’
