For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
King James Version (public domain)
Traditionally attributed to Paul · 1st century AD · Thirteen epistles of the New Testament are traditionally attributed to him
23Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
24For the name of God is blasphemed among the Gentiles through you, as it is written.
25For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
26Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
27And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
