This adjective describes a state of quietness and tranquility, free from disturbance or tumult. It can characterize both external circumstances and internal dispositions. Paul uses it in his instructions about prayer for authorities, hoping believers might lead quiet and peaceful lives. The term suggests not merely absence of noise but freedom from chaos, persecution, or social upheaval. Classical usage applied it to calm lives, gentle medical treatments, and smooth surfaces—all sharing the quality of undisturbed peace.
