'Hear' in the Bible

How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher?

But I say, didn't they hear? Yes, most certainly, "Their sound went out into all the earth, their words to the ends of the world."

According as it is written, "God gave them a spirit of stupor, eyes that they should not see, and ears that they should not hear, to this very day."
