7. To say that speech is simple, is a praise of great weight. But because the haughty possess it not, they assert the more anxiously that they possess it, in order that they may be heard with less apprehension. And they declare that they are going to speak with pure intention, because they are afraid of their wicked duplicity being discovered. But they often also blend together truth and falsehood, that their falsehood may be the more speedily believed, from its being discerned that they speak the truth. Because then Eliu both said that he would speak with pure intention, and by calling his words ‘sentences’ ushered them in with applause, he subjoins the same ‘sentence’ which he promised.
These words mean, I do not speak so out of envy or jealousy. Even though the three friends said the same things as him, they did not do so in the same spirit or in order to defend God. Indeed also Judas and the eleven disciples expressed the same opinion about the vase of perfume, but not in the same spirit. Therefore, let us not examine the words but the intention with which each expresses himself. How the first wanted to overthrow him, whereas the latter wanted the opposite. Take heed: Elihu, who speaks last, expresses the thoughts that God is about to express, so that God may justify himself even better, once Job has heard the same remarks from his companions in bondage that he will afterwards hear from the Master. - "Commentary on Job 33.1–3"
