Titus 2:7-10

And in all things show yourself to be an example of good works, with purity in doctrine [having the strictest regard for integrity and truth], dignified, sound and beyond reproach in instruction, so that the opponent [of the faith] will be shamed, having nothing bad to say about us. Urge bond-servants to be subject to their own masters in everything, to be pleasing and not talk back, not stealing [things, regardless of value], but proving themselves trustworthy, so that in every respect they will adorn and do credit to the teaching of God our Savior.
