The Hebrew verb nuwt means to quake, to tremble, to shake, or to waver. It describes an involuntary physical response to fear, distress, or the overwhelming presence of something powerful. The word conveys instability and vulnerability in the face of a greater force.
This verb appears in poetic contexts describing the human response to suffering and divine judgment. When used of people, it depicts the instinctive trembling that accompanies deep grief or terror. Theologically, the concept of trembling before God reflects the proper posture of creatures before their Creator — an acknowledgment of His awesome power and holiness.
