reverence (v.2) = gravity, seemliness, free from excess, dignified
Wuest’s translation — I exhort therefore, first of all, that petitions be made continually for personal needs, prayers, intercessions, giving of thanks on behalf of all, on behalf of kings and all those holding high positions, in order that a quiet and peaceful life we may be leading in all godliness and becoming deportment. Wuest, page 40
