For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Circumcision has value if you observe the law, but if you break the law, you have become as though you had not been circumcised.
Περιτομὴ μὲν γὰρ ὠφελεῖ, ἐὰν νόμον πράσσῃς· ἐὰν δὲ παραβάτης νόμου ᾖς, ἡ περιτομή σου ἀκροβυστία γέγονεν.
Peritomē men gar ōphelei, ean nomon prassēs· ean de parabatēs nomoy ēs, ē peritomē soy akrobystia gegonen.
