For there are many unruly and vain talkers and deceivers, specially they of the circumcision: There are many unruly - Persons who will not receive the sound doctrine, nor come under wholesome discipline.
Vain talkers - Empty boasters of knowledge, rights, and particular privileges; all noise, empty parade, and no work.
Deceivers - Of the souls of men by their specious pretensions.
They of the circumcision - The Judaizing teachers, who maintained the necessity of circumcision, and of observing the rites and ceremonies of the Mosaic law, in order to the perfecting of the Gospel.
