Matthew 13:13-15

13This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. 14Indeed, in their case the prophecy of Isaiah is fulfilled that says: “‘“You will indeed hear but never understand, and you will indeed see but never perceive.” 15For this people’s heart has grown dull, and with their ears they can barely hear, and their eyes they have closed, lest they should see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them.’
