Titus 1:10-15

10For there are many and disorderly vain speakers and deceivers of people's minds, specially those of [the] circumcision,

11who must have their mouths stopped, who subvert whole houses, teaching things which ought not [to be taught] for the sake of base gain.

12One of themselves, a prophet of their own, has said, Cretans are always liars, evil wild beasts, lazy gluttons.

13This testimony is true; for which cause rebuke them severely, that they may be sound in the faith,

14not turning [their] minds to Jewish fables and commandments of men turning away from the truth.

15All things [are] pure to the pure; but to the defiled and unbelieving nothing [is] pure; but both their mind and their conscience are defiled.
