'Circumcision' in the Bible

For circumcision is of value if you do the law, but if you should be a transgressor of the law, your circumcision has become uncircumcision.

Therefore, if the uncircumcised person follows the requirements of the law, will not his uncircumcision be credited for circumcision?

And the uncircumcised person by nature who carries out the law will judge you who, [though provided] with {the precise written code} and circumcision [are] a transgressor of the law.

For the Jew is not {one outwardly}, nor [is] circumcision {outwardly}, in the flesh.

But the Jew {is one inwardly}, and circumcision [is] of the heart, by the Spirit, not by the letter, whose praise [is] not from people but from God.

Therefore, what [is] the advantage of the Jew, or what [is] the use of circumcision?

And he received the sign of circumcision [as] a seal of the righteousness by faith which [he had] {while uncircumcised}, so that he could be the father of all who believe {although they are uncircumcised}, so that righteousness could be credited to them,

and the father {of those who are circumcised} to those who are not only from the circumcision, but who also follow in the footsteps of the faith of our father Abraham {which he had while uncircumcised}.

For I say, Christ has become a servant of the circumcision on behalf of the truth of God, in order to confirm the promises to the fathers,
