Romans 2:20-22

New Catholic Bible

²⁰ an instructor of the foolish, and a teacher of the simple because in the Law you have the embodiment of knowledge and truth.

²¹ You, then, who teach others, do you not teach yourself? You who preach against stealing, are you yourself a thief? ²² You who forbid adultery, are you yourself an adulterer? You who abhor idols, do you commit sacrilege?
