The reason I talk to them in parables is that they look without seeing and listen without hearing or understanding. So in their case what was spoken by the prophet Isaiah is being fulfilled: Listen and listen, but never understand! Look and look, but never perceive! This people’s heart has grown coarse, their ears dulled, they have shut their eyes tight to avoid using their eyes to see, their ears to hear, their heart to understand, changing their ways and being healed by me. ‘But blessed are your eyes because they see, your ears because they hear! In truth I tell you, many prophets and upright people longed to see what you see, and never saw it; to hear what you hear, and never heard it. ‘So pay attention to the parable of the sower.
Matthew 13: 13-18
