C. F. Keil and Franz Delitzsch on Job 40:1-3

Job 40:1-3   1  Then Jehovah answered Job, and said:   2  Will now the censurer contend with the Almighty?

Let the instructor of Eloah answer it!   3  Then Job answered Jehovah, and said:

With Job 40:1; Job 38:1 is again taken up, because the speech of Jehovah has now in some measure attained the end which was assigned to it as an answer to Job’s outburst of censure. רב is inf. abs., as Jdg 11:25; it is left to the hearer to give to the simple verbal notion its syntactic relation in accordance with the connection; here it stands in the sense of the fut. (comp. 2Ki 4:43): num litigabit, Ges. §131, 4, b. The inf. abs. is followed by יסּור as subj., which (after the form שׁכּור) signifies a censurer and fault-finder, moomeetee's. The question means, will Job persist in this contending with God? He who sets God right, as though he knew everything better than He, shall answer the questions put before him.
