Titus 1:10-15

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. To the pure all things are pure, but to those who are defiled and unbelieving nothing is pure; but even their mind and conscience are defiled.
