When the scourge brings sudden death, He mocks the despair of the innocent.
Here Job touches briefly upon the main point now in dispute between him and his friends. They maintained that those who are righteous and good always prosper in this world, and none but the wicked are in misery and distress; he asserted, on the contrary, that it is a common thing for the wicked to prosper and the righteous to be greatly afflicted.
Commenting on Job 9:22-24
The earth is given into the hands of the wicked,.... Either the wicked one, Satan, as Jarchi and Bar Tzemach, who is the god of this world; or some wicked tyrant, as Nimrod, or some other known by Job in his time, to whom he may have respect; or wicked men in general, who for the most part have the greatest share of the earth...
If--Rather, "While (His) scourge slays suddenly (the wicked, Job 9:22), He laughs at (disregards; not derides) the pining away of the innocent." The only difference, says Job, between the innocent and guilty is, the latter are slain by a sudden stroke, the former pine away gradually. The translation, "trial," does not express the antithesis to "slay suddenly," as "pining away" does [UMBREIT].
