'Circumcision' in the Bible

Beware of the dogs, beware of the evil workers, beware of the false circumcision;

For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.

circumcision on the eighth day! of the race of Israel! of the tribe of Benjamin! a Hebrew of Hebrews! according to law a Pharisee!
