Titus 2:7-10

in all things showing yourself to be a pattern of good works; in doctrine showing integrity, reverence, incorruptibility, sound speech that cannot be condemned, that one who is an opponent may be ashamed, having nothing evil to say of you. Exhort bondservants to be obedient to their own masters, to be well pleasing in all things, not answering back, not pilfering, but showing all good fidelity, that they may adorn the doctrine of God our Savior in all things.
