Jamieson, Fausset and Brown on Job 3:2

2. spake--Hebrew, "answered," that is, not to any actual question that preceded, but to the question virtually involved in the case. His outburst is singularly wild and bold (Jr 20:14). To desire to die so as to be free from sin is a mark of grace; to desire to die so as to escape troubles is a mark of corruption. He was ill-fitted to die who was so unwilling to live. But his trials were greater, and his light less, than ours.
