Comentario citado sobre Isaías 28:6

With the completion of two rounds, six [orations] in each round, (Leviticus 24:6) the first concerning the suffering of the righteous and the second the prosperity of the wicked; and after the wrangler Job had triumphed over all of them with his answers, his bows and his arrows (Genesis 48:22); Eliphaz now tries, for one last time, to fit his arrow to the bowstring (Psalms 11:2) in order to counter-attack at the gate (Isaiah 28:6) in a single speech that addresses both issues. In doing so, he devises a new approach, one with fine insight and knowledge (Psalms 119:66), according to which it is out of wisdom on God's part, and with particular intent, that the rewards of the righteous and the punishments of the wicked are not immediately disbursed in this world. This is done so as to ensure that the worship of God may be selfless, motivated neither by love of reward nor by fear of punishment.

Bildad too makes one final effort to find a remedy (Jeremiah 51:8) for the theories he had put forward: his hypothesis that reparation is ultimately made for the suffering of the righteous, and his assertion with regard to the prosperity of the wicked, that the greater part of their punishment—the perdition of their souls and that of their offspring—is reserved for the world to come. Though Job had rebuffed all of this, Bildad now gathers his strength (Isaiah 27:5) to re-engage battle at the gate (Isaiah 28:6) in the following way:

Overwhelmed by the power of his arguments, Job’s three companions were left wordless at the end of his oration.¹It had not occurred to any of them that Job was undergoing a trial. Each had tried to justify God at the expense of Job's innocence or integrity. Eliphaz had accused him of sinning openly; Zophar, of having sinned secretly; Bildad, of not being all he seemed. But Job had remained steadfast under all their attacks. They had now exhausted all their arguments. However, at this point a brave warrior (1Samuel 16:18) joins the campaign (1Samuel 17:20); who speaks with understanding...God being with him. Addressing the debaters present, Elihu turns back the tide of war (Isaiah 28:6), and displaying his strength (1Samuel 14:48) he reveals the truth concerning these questions. He formulates and scrutinizes them (Job 28:27), with the spirit of God that is upon him (Judges 3:10 et alia); and with the secret of the holy ones (Psalms 89:8) and of the perfect Forms (Job 37:16) in his mind. Until at the conclusion of his speech he discloses God’s secret (Jeremiah 23:18); what had happened when the Sons of God assembled before the Lord and Satan too had joined them (Job 1:6), as was related at the beginning of the book. Thus, the conclusion of the debate is to be found in the book’s Prologue. And all of this was known to Elihu from the secret God reveals to those that fear Him.²Psalms 25:14. Malbim offers no explanation why, if he was present throughout the debate, Elihu is mentioned neither in the Prologue nor in the Epilogue. This is one of the reasons that modern exegetes have regarded Elihu's speech as a later interpolation and not part of the original text of the Book.
