17 But if you are called by name a Jew, and you rest upon the law, and you find glory in God,
18 and you have known his will, and you demonstrate the more useful things, having been instructed by the law:
19 you become confident within yourself that you are a guide to the blind, a light to those who are in darkness,
20 an instructor to the foolish, a teacher to children, because you have a type of knowledge and truth in the law.
21 As a result, you teach others, but you do not teach yourself. You preach that men should not steal, but you yourself steal.
22 You speak against adultery, but you commit adultery. You abominate idols, but you commit sacrilege.
23 You would glory in the law, but through a betrayal of the law you dishonor God.
