17 Behold, thou art called a Jew, and restest in the law, and makest thy boast of God, 18 And knowest his will, and approvestd the things that are more excellent, being instructed out of the law; 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.
