"For the ear tests words as the palate tastes food."  Elihu encourages us to listen carefully and meditatively to God's words and God's wisdom.  He helps Job and therefure us to remove the scales from our eyes that we might hear and see more clearly the way and will of God in the areas that God would have us correct on this journey to the Kingdom of God.  The righteous children of God must listen very carefully to the inspiration and instruction of God.
