6. Like the wild asses (Job 24:5) they (these Bedouin robbers) reap (metaphorically) their various grain (so the Hebrew for "corn" means). The wild ass does not let man pile his mixed provender up in a stable (Isa 30:24); so these robbers find their food in the open air, at one time in the desert (Job 24:5), at another in the fields.
      the vintage of the wicked--Hebrew, "the wicked gather the vintage"; the vintage of robbery, not of honest industry. If we translate "belonging to the wicked," then it will imply that the wicked alone have vineyards, the "pious poor" (Job 24:4) have none. "Gather" in Hebrew, is "gather late." As the first clause refers to the early harvest of corn, so the second to the vintage late in autumn.
