Titus 1:9-11

9 holding — according to the teaching — to the stedfast word, that he may be able also to exhort in the sound teaching, and the gainsayers to convict;

10 for there are many both insubordinate, vain-talkers, and mind-deceivers — especially they of the circumcision —

11 whose mouth it behoveth to stop, who whole households do overturn, teaching what things it behoveth not, for filthy lucre's sake.
