Jamieson, Fausset & Brown

That (Job 18:4) cannot be. The decree of God is unalterable, the light (prosperity) of the wicked shall at length be put out. his fire--alluding to Arabian hospitality, which prided itself on welcoming the stranger to the fire in the tent, and even lit fires to direct him to it. The ungodly shall be deprived of the means to show hospitality. His dwelling shall be dark and desolate!
