Romans 2:19-21

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

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

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