Matthew 13:10-15

And the disciples came and said to Him, “Why do You speak to them in parables?” Jesus answered them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted. For whoever has, to him more shall be given, and he will have an abundance; but whoever does not have, even what he has shall be taken away from him. Therefore I speak to them in parables; because while seeing they do not see, and while hearing they do not hear, nor do they understand. In their case the prophecy of Isaiah is being fulfilled, which says, ‘YOU WILL KEEP ON HEARING, BUT WILL NOT UNDERSTAND; YOU WILL KEEP ON SEEING, BUT WILL NOT PERCEIVE; FOR THE HEART OF THIS PEOPLE HAS BECOME DULL, WITH THEIR EARS THEY SCARCELY HEAR, AND THEY HAVE CLOSED THEIR EYES, OTHERWISE THEY WOULD SEE WITH THEIR EYES, HEAR WITH THEIR EARS, AND UNDERSTAND WITH THEIR HEART AND RETURN, AND I WOULD HEAL THEM.’
