Job 5:9 - Joseph Benson’s Commentary on the Old and New Testaments

Which doth great things and unsearchable Here Eliphaz enters upon a discourse of the infinite perfection of God's nature and works; which he does as an argument to enforce the exhortation to seek and commit his cause to God, Job 5:8, because God was infinitely able either to punish him yet far worse, if he continued to provoke him, or to raise him from the dust, if he humbly addressed himself to him: and that, by a representation of God's excellence and glory, and of that vast disproportion which was between God and Job, he might convince Job of his great sin in speaking so boldly and irreverently of him. Marvellous things Which (though common, and therefore neglected and despised, yet) are matter of wonder to the wisest men. The works of nature are mysteries: the most curious searches come far short of full discoveries; and the works of Providence are still more deep and unaccountable.
