Titus 1:9-11

9He must hold firmly to the faithful message as it has been taught, so that he will be able to give exhortation in such healthy teaching and correct those who speak against it.

10For there are many rebellious people, idle talkers, and deceivers, especially those with Jewish connections,

11who must be silenced because they mislead whole families by teaching for dishonest gain what ought not to be taught.
