[17] thou art called a Jew, and restest in the law, and makest thy boast of God, [18] And knowest his will, and approvest the things that are more excellent, being instructed out of the law; [19] And art confident that thou thyself 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. [21] Thou therefore which teachest another, teachest thou not thyself? thou that preachest not steal, [22] Thou that sayest not 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?
