This noun describes vehement emotion or excitement, particularly terror, alarm, or sudden fright. It denotes the physical and emotional reaction to something startling or threatening. Peter uses this term to encourage Christian wives not to give way to fear even in the face of suffering or intimidation. The multilingual glosses emphasize the fear dimension: Spanish 'temor' (fear), pointing to the emotional disturbance that can trouble the heart. Peter's exhortation echoes Sarah's example of faithful courage in the face of uncertainty.
