Elihu appears to represent the new "wisdom" which came to Hebrew thinkers in the period of the exile; and there are certain opinions embodied in his address which must have been formed during an exile that brought many Jews to honour. The reading of affliction given is one following the discovery that the general sinfulness of a nation may entail chastisement on men who have not personally been guilty of great sin, yet are sharers in the common neglect of religion and pride of heart, and further that this chastisement may be the means of great profit to those who suffer. It would be harsh to say the tone is that of a mind which has caught the trick of "voluntary humility," of pietistic self-abasement. Yet there are traces of such a tendency, the beginning of a religious strain opposed to legal self-righteousness, running, however, very readily to excess and formalism. Elihu, accordingly, appears to stand on the verge of a descent from the robust moral vigour of the original author towards that low ground in which false views of man's nature hinder the free activity of faith.
The note struck by the Book of Job had stirred eager thought in the time of the exile. Just as in the Middle Ages of European history the Divine Comedy of Dante was made a special study, and chairs were founded in universities for its exposition, so less formally the drama of Job was made the subject of inquiry and speculation. We suppose then that among the many who wrote on the poem, one acting for a circle of thinkers incorporated their views in the text. He could not do so otherwise than by bringing a new speaker on the stage. To add anything to what Eliphaz or Bildad or Job had said would have prevented the free expression of new opinion. Nor could he without disrespect have inserted the criticism after the words of Jehovah. Selecting as the only proper point of interpolation the close of the debate between Job and the friends, the scribe introduced the Elihu portion as a review of the whole scope of the book, and may indeed have subtly intended to assail as entirely heterodox the presupposition of Job's integrity and the Almighty's approval of his servant. That being his purpose, he had to veil it in order to keep the discourse of Elihu in line with the place assigned to him in the dramatic movement. The contents of the prologue and epilogue and the utterance of the Almighty from the storm affect, throughout, the added discourse. But to secure the unity of the poem the writer makes Elihu speak like one occupying the same ground as Eliphaz and the others, that of a thinker ignorant of the original motive of the drama; and this is accomplished with no small skill. The assumption is that reverent thought may throw new light, far more light than the original author possessed, on the case as it stood during the colloquies. Elihu avoids assailing the conception of the prologue that Job is a perfect and upright man approved by God. He takes the state of the sufferer as he finds it, and inquires how and why it is, what is the remedy. There are pedantries and obscurities in the discourse, yet the author must not be denied the merit of a careful and successful attempt to adapt his character to the place he occupies in the drama. Beyond this, and the admission that something additional is said on the subject of Divine discipline, it is needless to go in justifying Elihu's appearance. One can only remark with wonder in passing that Elihu should ever have been declared the Angel Jehovah, or a personification of the Son of God.
The narrative verses which introduce the new speaker state that his wrath was kindled against Job because he justified himself rather than God, and against the three friends because they had condemned Job and yet found no answer to his arguments. The mood is that of a critic rather hot, somewhat too confident that he knows, beginning a task that requires much penetration and wisdom. But the opening sentences of the speech of Elihu betray the need the writer felt to justify himself in making his bold venture.
