Titus 1:10-15

10For there are many rebellious men who are empty talkers [just windbags] and deceivers; especially those of the circumcision [those Jews who insist that Gentile believers must be circumcised and keep the Law in order to be saved].

11They must be silenced, because they are upsetting whole families by teaching things they should not teach for the purpose of dishonest financial gain.

12One of them [Epimenides, a Cretan], a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.”

13This description is true. So rebuke them sharply so that they will be sound in the faith and free from doctrinal error,

14not paying attention to Jewish myths and the commandments and rules of men who turn their backs on the truth.

15To the pure, all things are pure; but to the corrupt and unbelieving, nothing is pure; both their mind and their conscience are corrupted.
