Job 21:1 - Joseph Benson’s Commentary on the Old and New Testaments

But Job answered and said It has been thought strange that Job should never resume the argument of a resurrection, which was so full of piety and conviction; but, when resuming the dispute with his friends, should stick to that he first set out with. Whether this be the case or not, we shall see in the course of our observations. But if it be, a very sufficient reason may be assigned for it. For, if one such appeal as this, made in the most solemn manner, would not convince them of his innocence, he had reason to think it would be much the same, if he had repeated it a second and a third time. He had, therefore, no other resource left, but to follow the argument with which he had begun; namely, to combat the false principle upon which they were so forward to condemn him: and this he does effectually throughout the present chapter, by showing that many wicked men live long and prosperously, and at last die in apparent peace, and are buried with great pomp; which shows that this life is not the proper state of retribution, but that men shall be judged and recompensed hereafter.
