That is, the abodes of destruction and of the dead. "Death" put for Sheol (Job 30:23; Job 26:6; Psalms 9:13).
We have [only] heard—the report of her. We have not seen her. In the land of the living (Job 28:13) the workings of Wisdom are seen, though not herself. In the regions of the dead she is only heard of, her actings on nature not being seen (Ecclesiastes 9:10).
