Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all.
Ἴδε, ἐγὼ Παῦλος λέγω ὑμῖν ὅτι ἐὰν περιτέμνησθε, Χριστὸς ὑμᾶς οὐδὲν ὠφελήσει.
Ide, egō Paylos legō ymin oti ean peritemnēsthe, Christos ymas oyden ōphelēsei.
