He thought his own people would understand that God was delivering them through him, but they did not understand.

when he said, ‘Go to this people and say, “You will keep on hearing, but will never understand, and you will keep on looking, but will never perceive.

For the heart of this people has become dull, and their ears are hard of hearing, and they have closed their eyes, so that they would not see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them.”’
