Romans 2:22

19 and art confident that thou thyself art a guide of the blind, a light of them that are in darkness,

20 a corrector of the foolish, a teacher of babes, having in the law the form of knowledge and of the truth;

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

22 thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou rob temples?

23 thou who gloriest in the law, through thy transgression of the law dishonorest thou God?

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

25 For circumcision indeed profiteth, if thou be a doer of the law: but if thou be a transgressor of the law, thy circumcision is become uncircumcision.
