King James Dictionary

Concision A cutting off; a false circumcision. Finally, my brethren, rejoice in the Lord. To write the same things to you, to me indeed is not grievous, but for you it is safe. Beware of dogs, beware of evil workers, beware of the CONCISION. For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh. (Phi 3,3)
