Romans 2:17-21

You who call yourselves Jews are relying on God’s law, and you boast about your special relationship with him. You know what he wants; you know what is right because you have been taught his law. You are convinced that you are a guide for the blind and a light for people who are lost in darkness. You think you can instruct the ignorant and teach children the ways of God. For you are certain that God’s law gives you complete knowledge and truth. Well then, if you teach others, why don’t you teach yourself? You tell others not to steal, but do you steal?
