Titus 1:9-14

holding to the faithful word which is according to the teaching, that he may be able both to exhort in the sound doctrine, and to convict the gainsayers. For there are many unruly men, vain talkers and deceivers, specially they of the circumcision, whose mouths must be stopped; men who overthrow whole houses, teaching things which they ought not, for filthy lucre’s sake. One of themselves, a prophet of their own, said, Cretans are always liars, evil beasts, idle gluttons. This testimony is true. For which cause reprove them sharply, that they may be sound in the faith, not giving heed to Jewish fables, and commandments of men who turn away from the truth.
