John Chrysostom
‘Dhnu’ - meaning without exertion: he merely desired, and their existence came to an end. This expression metaphorically describes the behavior of the wrathful, who, rather than offering correction, inflate their own importance. The phrase ‘Between morning and evening they dissolve’ (from morning ... to evening ... they are not) indicates either that Job faced all trials within a single day or emphasizes that God does not require time when administering justice to the unrighteous.
