Romans 2:22

20An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.

21Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?

22Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

23Thou that makest thy boast of the law, through breaking the law dishonourest thou God?

24For the name of God is blasphemed among the Gentiles through you, as it is written.
