Romans 2:20

And knowest his will, and approvest the things that are more excellent, being instructed out of the law;

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

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

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