'Ear' in the Bible

See that you give ear to his voice which comes to you. For if those whose ears were shut to the voice which came to them on earth did not go free from punishment, what chance have we of going free if we give no attention to him whose voice comes from heaven?

Give ear to those who are rulers over you, and do as they say: for they keep watch over your souls, ready to give an account of them; let them be able to do this with joy and not with grief, because that would be of no profit to you.
