This Hithpael verb appears in Job 9:6, describing how the earth's pillars shudder when God shakes the earth in his anger. It's violent, involuntary trembling—the kind that comes from cosmic-level disturbance. The image is of the very foundations of creation responding to divine power with convulsive shaking. Job uses this metaphor to illustrate God's overwhelming might: if even the pillars that support the world tremble at His touch, how can a human being hope to stand in legal dispute with Him? The term captures existential terror at the cosmic scale.
