Romans 2:17-21

But as for you who have the name of Jew, and are resting on the law, and take pride in God, And have knowledge of his desires, and are a judge of the things which are different, having the learning of the law, In the belief that you are a guide to the blind, a light to those in the dark, A teacher of the foolish, having in the law the form of knowledge and of what is true; You who give teaching to others, do you give it to yourself? you who say that a man may not take what is not his, do you take what is not yours?
