'Hear' in the Bible

It is not those that merely hear the Law read who are righteous in the sight of God, but it is those that obey the Law who will be pronounced righteous.

But how are they to call on One in whom they have not believed? And how are they to believe in One whose voice they have never heard? And how are they to hear without a preacher?

And so Scripture says, "God has given them a spirit of drowsiness--eyes to see nothing with and ears to hear nothing with--even until now."
