Adam Clarke, on Titus 1:10

“For there are also many disobedient, vain talkers, and seducers: especially they who are 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.”
