Romans 2:19-23

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?
