Romans 2:19-25

19and hast confidence that thou thyself art a leader of the blind, a light of those who [are] in darkness,

20an instructor of the foolish, a teacher of babes, having the form of knowledge and of truth in the law:

21thou then that teachest another, dost thou not teach thyself? thou that preachest not to steal, dost thou steal?

22thou that sayest [man should] not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

23thou who boastest in law, dost thou by transgression of the law dishonour 1God?

24For the name of 2God is blasphemed on your account among the nations, according as it is written.

25For circumcision indeed profits if thou keep [the] law; but if thou be a law-transgressor, thy circumcision is become uncircumcision.
