Titus 1:9-13

He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.

10 For there are many who are insubordinate, empty talkers and deceivers, especially those of the circumcision party. 11 They must be silenced, since they are upsetting whole families by teaching for shameful gain what they ought not to teach. 12 One of the Cretans, a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.” 13 This testimony is true. Therefore rebuke them sharply, that they may be sound in the faith,
