Titus 1:10

1:9 holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict.

1:10 For there are many insubordinate, both idle talkers and deceivers, especially those of the circumcision,

1:11 whose mouths must be stopped, who subvert whole households, teaching things which they ought not, for the sake of dishonest gain.
