Romans 2:21

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

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

Thou therefore which 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 commit sacrilege?

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

Do read the surrounding verses too, because the context often says more than a single verse.
