Acts 15:24

Some men came down from Judea and began teaching the brothers, “Unless you are circumcised according to the custom of Moses, you cannot be saved.”

and they have been told about you, that you are teaching all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children nor to walk according to the customs.

Was any man called when he was already circumcised? He is not to become uncircumcised. Has anyone been called in uncircumcision? He is not to be circumcised.

which is really not another, only there are some who are disturbing you and want to distort the gospel of Christ.

But this was because of the false brothers secretly brought in, who had sneaked in to spy out our freedom which we have in Christ Jesus, in order to enslave us.
