'Circumcised' in the Bible

but not even Titus, who is with me, being a Greek, was compelled to be circumcised --

lo, I Paul do say to you, that if ye be circumcised, Christ shall profit you nothing;

and I testify again to every man circumcised, that he is a debtor to do the whole law;

as many as are willing to make a good appearance in the flesh, these constrain you to be circumcised -- only that for the cross of the Christ they may not be persecuted,

for neither do those circumcised themselves keep the law, but they wish you to be circumcised, that in your flesh they may glory.
