Titus 2:7-10

in all things show yourself to be an example of good deeds, with purity in doctrine, dignified, sound in speech which is beyond reproach, so that the opponent will be put to shame, having nothing bad to say about us. Urge bondslaves to be subject to their own masters in everything, to be well-pleasing, not argumentative, not pilfering, but showing all good faith so that they will adorn the doctrine of God our Savior in every respect.
