Titus 1:9-11

ISV(i) 9 He must be devoted to the trustworthy message that agrees with what we teach, so that he may be able to encourage others with healthy doctrine and refute those who oppose it.
10 Guard What is TrueFor there are many people who are rebellious, especially those who are converts from Judaism. They speak utter nonsense and deceive people. 11 They must be silenced, because they are the kind of people who ruin whole families by teaching what they should not teach in order to make money in a shameful way.
