17. Indeed you are called a Jew, and rest in the law, and make your boast in God.
18. You know His will and approve the things that are more excellent, because you are instructed in the law.
19. You are confident that you are a guide to the blind, a light to those who are in darkness,
20. an instructor of the foolish, and a teacher of babes, who have the full content of knowledge and truth in the law:
21. You, therefore, who teach another, do you not teach yourself? You who preach not to steal, do you steal?
