Romans 2:19-21

Revised Standard Version

¹⁹ and if you are sure that you are a guide to the blind, a light to those who are in darkness, ²⁰ a corrector of the foolish, a teacher of children, having in the law the embodiment of knowledge and truth— ²¹ you then who teach others, will you not teach yourself? While you preach against stealing, do you steal?
