Jamieson, Fausset and Brown on Job 14:22

22. "Flesh" and "soul" describe the whole man. Scripture rests the hope of a future life, not on the inherent immortality of the soul, but on the restoration of the body with the soul. In the unseen world, Job in a gloomy frame anticipates, man shall be limited to the thought of his own misery. "Pain is by personification, from our feelings while alive, attributed to the flesh and soul, as if the man could feel in his body when dead. It is the dead in general, not the wicked, who are meant here."
