'Attention' in the Bible

For this reason there is the more need for us to give attention to the things which have come to our ears, for fear that by chance we might be slipping away.

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?
