'Heard' 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? And how will they hear without a preacher?

But I say, surely they have never heard, have they? Indeed they have;“Their voice has gone out into all the earth,And their words to the ends of the world.”

but as it is written,“They who had no news of Him shall see,And they who have not heard shall understand.”
