CON-CIS'ION, n. [s as z. Low L. concisio, from concisum, concido, to cut off; It. concisione.]

Literally, a cutting off. Hence, In Scripture, the Jews, or those who adhered to circumcision, which, after our Savior's death, was no longer a seal of the covenant, but a mere cutting of the flesh. Beware of dogs; beware of the concision. – Phil. iii.
