36:15-23 Elihu shows that Job caused the continuance of his own trouble. He cautions him not to persist in frowardness. Even good men need to be kept to their duty by the fear of God's wrath; the wisest and best have enough in them to deserve his stroke. Let not Job continue his unjust quarrel with God and his providence. And let us never dare to think favourably of sin, never indulge it, nor allow ourselves in it. Elihu thinks Job needed this caution, he having chosen rather to gratify his pride and humour by contending with God, than to mortify them by submitting, and accepting the punishment. It is absurd for us to think to teach Him who is himself the Fountain of light, truth, knowledge, and instruction. He teaches by the Bible, and that is the best book; teaches by his Son, and he is the best Master. He is just in all proceedings.

22-25. God is not to be impiously arraigned, but to be praised for His might, shown in His works.

exalteth—rather, doeth lofty things, shows His exalted power [Umbreit] (Ps 21:13).

teacheth—(Ps 94:12, &c.). The connection is, returning to Job 36:5, God's "might" is shown in His "wisdom"; He alone can teach; yet, because He, as a sovereign, explains not all His dealings, forsooth Job must presume to teach Him (Isa 40:13, 14; Ro 11:34; 1Co 2:16). So the transition to Job 36:23 is natural. Umbreit with the Septuagint translates, "Who is Lord," wrongly, as this meaning belongs to later Hebrew.
