Matthew Henry Presbyterian @wholebiblehenry

Job's friends all of them went upon this principle, that wicked people cannot prosper long in this world, but some remarkable judgment or other will suddenly light on them: Zophar had concluded with it, that the eyes of the wicked shall fail, Job 11:20.

Who knoweth not in all these,.... Or "by" or "from all these" (o) creatures; what man is there so stupid and senseless, that does not discern, or cannot learn, even from irrational creatures, the above things, even what Zophar had discoursed concerning God and his perfections, his power, wisdom and providence?
