Matthew 13:14; Matthew 13:15

14 So the prophecy of Isaiah applies to them: "This people will listen and listen, but not understand; they will look and look, but not see,

15 because their minds are dull, and they have stopped up their ears and have closed their eyes. Otherwise, their eyes would see, their ears would hear, their minds would understand, and they would turn to me, says God, and I would heal them.'
