Verse 3. -
My words shall be of the uprightness of my heart. Moreover, whatever I say will be said with entire sincerity. My heart is upright, and I shall speak "from the uprightness of my heart," without pretence, deception, or concealment of any kind.
And my lips shall utter knowledge clearly. I shall say only
what I know and shall endeavour to say it simply and clearly, so that no one can mistake my meaning.
33:1-7 Job had desired a judge to decide his appeal. Elihu was one according to his wish, a man like himself. If we would rightly convince men, it must be by reason, not by terror; by fair argument, not by a heavy hand.
My words shall be of the uprightness of my heart,.... Not that the uprightness of his heart, or his own personal integrity, should be the subject of his discourse; but what he should say would be in or out of the uprightness of his heart, with all sincerity and faithfulness; what would be the real sentiments of his mind, and not proceed from a double or insincere heart:
and my lips shall utter knowledge clearly; what knowledge he had of God, and of the perfections of his nature, and of his works in nature and grace, and of his dealings in a providential way with the sons of men; and what knowledge he had of Christ, his person, office, and grace somewhat of which speaks in this chapter; and such sort of knowledge is to be uttered, to be published, and made known to the good of others; and not to be concealed, and hid, or held, as in a prison, in unrighteousness; and to be uttered clearly, plainly, and distinctly, in words intelligible, and easy to be understood; and not in ambiguous terms, or in words of a double meaning; or which are abstruse and intricate, and serve rather to make the mysteries of Providence and grace more dark and obscure than to explain them; integrity of heart, and perspicuity of language, serve much to recommend a speaker, and both are expressed in this verse.
