An abstract noun denoting the physical response of shuddering or trembling from horror and dread. Job describes how even remembering his affliction makes him tremble, and 'shuddering seizes my flesh' (21:6). The psalmist cries that 'fear and trembling come upon me, and shuddering overwhelms me' when contemplating enemies' violence (55:5). Isaiah depicts the night of pleasure turned to 'shuddering'—terror replacing joy (21:4). Ezekiel warns that 'shuddering will be on all faces' when judgment comes (7:18). The term captures visceral terror—the involuntary bodily reaction to overwhelming fear, whether from past trauma, present danger, or anticipated judgment.
