Behold, God exalteth by his power - The object of Elihu is now to direct the attention of Job to God, and to show him that he has evinced such power and wisdom in his works, that we ought not to presume to arraign him, but should bow with submission to his will. He remarks, therefore, that God “exalts,” or rather that God is “exalted,” or “exalts himself” (ישׂגיב yaśagiyb) by his power. In the exhibition of his power, he thus shows that he is great, and that people ought to be submissive to him. In support of this, he appeals, in the remainder of his discourse, to the “works” of God as furnishing extraordinary proofs of power, and full demonstration that God is exalted far above man.
Who teacheth like him? - The Septuagint renders this, δυνάστης dunastēs - “Who is so powerful as he?” Rosenmuller and Umbreit render it Lord: “Who is Lord like him?” But the Hebrew word (מורה môreh) properly means “one who instructs,” and the idea is, that there is no one who is qualified to give so exalted conceptions of the government of God as he is himself. The object is to direct the mind to him as he is revealed in his works, in order to obtain elevated conceptions of his government.
