Commentators explain that for Job, the grave represents a profound release from earthly suffering. In death, prisoners are freed from their chains and no longer hear the voice of their 'oppressor' or 'taskmaster.' Scholars like Albert Barnes and John Gill note that death is the great equalizer, where the oppressed find tranquility and rest on the same level as those who once imprisoned them. It is a state of ultimate, peaceful freedom from worldly injustice.
