Job 21:31 - Joseph Benson’s Commentary on the Old and New Testaments

Who shall declare his way? That is, his wicked course and actions, and whither they lead him; to his face That is, plainly, and while he lives, as the same phrase is used Deuteronomy 7:10. His power and splendour are so great that scarcely any man dare reprove him for his sin, or show him his danger. And who shall repay him what he hath done? No man can bring him to an account or punishment. Job is here pursuing the same way of reasoning which he did before, and showing that the wicked mighty man is so far from being always punished in this world, that he often does what he pleases without any to control him, or so much as open their lips against him. And that such a one shall at last go down to the grave in peace, and be buried with great pomp.
