Matthew 13:14-15

14 With them indeed is fulfilled the prophecy of Isaiah that says: "You will indeed listen, but never understand, and you will indeed look, but never perceive.

15 For this people's heart has grown dull, and their ears are hard of hearing, and they have shut their eyes; so that they might not look with their eyes, and listen with their ears, and understand with their heart and turn— and I would heal them.'
