17 But if you call yourself a Jew and drely on the law and boast in God 18 and know his will and approve what is excellent, because you are instructed from the law; 19 and if you are sure that you yourself are ea guide to the blind, a light to those who are in darkness, 20 an instructor of the foolish, a teacher of children, having in the law fthe embodiment of gknowledge and truth—21 hyou then who teach others, do you not teach yourself? While you preach against stealing, do you steal? 22 You who say that one must not commit adultery, do you commit adultery? You who abhor idols, do you irob temples? 23 You who jboast in the law kdishonor God by breaking the law.
