In the ancient book of Isaiah we can find this prophecy, where He predicts and describes those who do not believe in God:

“In them the prophecy of Isaiah is fulfilled, which says, ‘By hearing you will hear, and will in no way understand; Seeing you will see, and will in no way perceive; for this people’s heart has grown callous, their ears are dull of hearing, and they have closed their eyes; or else perhaps they might perceive with their eyes, hear with their ears, understand with their heart, and would turn again, and I would heal them.”
