Titus 1:9-14

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. For there are many insubordinate, both idle talkers and deceivers, especially those of the circumcision, whose mouths must be stopped, who subvert whole households, teaching things which they ought not, for the sake of dishonest gain. One of them, a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.” This testimony is true. Therefore rebuke them sharply, that they may be sound in the faith, not giving heed to Jewish fables and commandments of men who turn from the truth.
