Titus 1:10-13

For there are many rebellious men, empty talkers and deceivers, especially those of the circumcision, who must be silenced because they are upsetting whole families, teaching things they should not teach for the sake of sordid gain. One of themselves, a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.” This testimony is true. For this reason reprove them severely so that they may be sound in the faith
