Romans 2:24-25

For, “THE NAME OF GOD IS BLASPHEMED AMONG THE GENTILES BECAUSE OF YOU,” just as it is written [in Scripture]. [Is 52:5; Ezek 36:20] Circumcision [the sign of the covenant of Abraham] is indeed of value if you practice the Law; but if you habitually break the Law, your circumcision has become uncircumcision [it is meaningless in God’s sight].
