ציטירנדיקער פּירוש אויף איוב 38:3

At the close of the symposium, which had been based on thought and reasoning, the Lord appears to Job out of the tempest (Job 38:1), commanding that he be restored to himself (Job 38:3) and regain his strength, and that the afflictions be lifted from upon him and he join the Lord in debate. The appearance of God Himself effectively brings the whole argument to a close, for it patently proves that (Deuteronomy 4:35):

and the loins of kings I will loosen This is an expression of weakness and breaking strength, for girding the loins constitutes arming with strength. Comp. (Job 38:3) “Gird up your loins like a mighty man”; (Jer. 1:17) “And you gird up your loins”; (Job 12:21) “And the belt of the mighty He loosens”; an expression of breaking strength.

In his reply to God, Job paraphrases the very challenge God had made to him at the beginning of His oration (Job 38:2). It was because he did not want God's design to remain just a matter of faith, shrouded in mystery and uncertainty, that he had initiated the debate.
Responding to God in His own words (Job 38:3), Job explains that just as He had called for answers from Job, so Job had been seeking answers from God. Job's contention had been that rational answers should be given to the great issues raised by ethical monotheism; they should not be just matters of faith. And if man is unable to find these rational answers unaided, God ought to provide them.
