Romans 2:20-24

a corrector of the foolish, a teacher of the immature, possessing in the Law the embodiment of knowledge and of the truth—

you, therefore, who teach someone else, do you not teach yourself? You who preach that one is not to steal, do you steal?

You who say that one is not to commit adultery, do you commit adultery? You who loathe idols, do you rob temples?

You who boast in the Law, through your breaking the Law, do you dishonor God?

For “the name of God is blasphemed among the Gentiles because of you,” just as it is written.
