Titus 2:8-10

8and soundness of speech that cannot be condemned, so that those who oppose you may be ashamed because they have nothing bad to say about us. 9Teach slaves to be subject to their masters in everything, to try to please them, not to talk back to them,

10and not to steal from them, but to show that they can be fully trusted, so that in every way they will make the teaching about God our Savior attractive.
