Romans 2:17-21

¹⁷But if you call yourself a Jew and rely upon the Law and boast in God, ¹⁸and know His will and distinguish the things that matter, being instructed from the Law, ¹⁹and are confident that you yourself are a guide to people who are blind, a light to those in darkness, ²⁰a corrector of the foolish, a teacher of the immature, possessing in the Law the embodiment of knowledge and of the truth— ²¹you, therefore, who teach someone else, do you not teach yourself? You who preach that one is not to steal, do you steal?
