Whiston(i)
17 But if 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 thy self art a guide of the blind, a light of them who are in darkness,
20 An instructor of the foolish, a teacher of babes, who hast the form of knowledge, and of the truth in the law.
21 Thou therefore who teachest another, teachest thou not thy self? thou that preachest a man should not steal, dost thou steal?
22 Thou that sayst a man should not commit adultery, dost thou 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?
24 For the name of God is blasphemed among the Gentiles, through you, as it is written.
25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
26 Therefore, if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
28 For he is not a Jew, who is one outwardly; neither circumcision, which is outward in the flesh:
29 But he [is] a Jew, who is one inwardly; and circumcision [is] of the heart, in the spirit, not in the letter, whose praise is not of men but of God.
