What does Job Chapter 36 say, and which statements belong to its speaker?

Asking for brief patience, Eliu insisted that he had further truths to declare on God's behalf, promising to trace his knowledge from the beginning and prove his Maker righteous. He claimed his speech was entirely free from falsehood and founded upon sound truth. In Eliu’s argument, God, being mighty Himself, does not despise the mighty, yet He does not preserve the wicked and grants justice to the afflicted. His watchful eyes never leave the righteous, and places kings on thrones forever. If rulers or the upright fall into affliction, bound in chains and caught in cords of poverty, God uses their distress to show them their violent deeds, opening their ears to discipline and calling them to turn back from iniquity. If they heed His instruction and obey, they finish their days in prosperity and their years in glory; but if they refuse to listen, they fall by the sword and perish in their folly. By contrast, dissemblers and crafty men harbor divine wrath, refusing to cry for help when bound in affliction, so that their soul shall die in a storm and their life among the effeminate. Yet God faithfully delivers the poor from distress and opens their understanding through suffering.

In Eliu’s speech, applying this instruction directly to Job, Eliu declared that God sought to draw him out of the narrow confines of disaster into broad freedom, where his table would once more be filled with rich sustenance; a Challoner annotation explains that the narrow mouth figuratively represents hell or acute misery, out of which God restores the sufferer to happiness. Eliu warned that Job's case currently resembled the verdict of the wicked, saying that he would recover cause and judgment and urging him not to let wrath provoke him into oppressing others or allow a multitude of gifts to seduce him. He counseled Job to lay aside worldly greatness without tribulation, not to prolong the night that people may come up for them, and above all to beware of turning toward iniquity, which he had begun to pursue under the pressure of misery; an editorial annotation notes that Eliu charged Job with failing to revere God rightly amidst suffering and instead sliding into sinful complaint. Eliu proclaimed that God is exalted in power beyond all earthly lawgivers, asking who could scrutinize His ways or accuse Him of committing wrong, urging Job to remember that he does not know the work concerning which men have sung, while all behold Him afar off.

In Eliu’s speech, Eliu celebrated God's greatness exceeding our knowledge and inestimable years, which far exceed human comprehension. In Eliu’s account, God lifts drops of rain and pours down rain from the clouds that shroud the skies. He spreads the clouds like a vast pavilion tent, sends lightning flashes from on high, and covers also the ends of the sea. Through these atmospheric wonders God exercises judgment over nations while providing abundant food for mankind. Concealing lightning within His hands, He commands it to come again and shows His friend that it is His possession and that he may come up to it.
