Matthew Poole and continuators on Job 35:9

9. By reason of the multitude of oppressions, they make the oppressed to cry : they cry out by reason of the arm of the mighty .

Or, greatness. This Verse is supposed to contain an argument to prove what he said, v. 8. that one Mans wickedness may hurt another. But he rather seems to begin a new matter, and having answered one of Job's Objections to proceed to another which may be either 1. that which Job had oft complained of, that he cried to God, and God did not hear his cry, which Elihu answers by a Parallel case of men, crying out for oppression; whom yet God doth not hear, nor help, and that for just reasons. which he leaves to Job to apply to himself. Or, 2. that which Job had alledged, Chap. 24. 12. and which might seem to reflect upon God's Providence. This therefore Elihu repeats in this Verse, and answereth in the following.

Not onely to murmur and complain, but to cry out by reason of sore oppression, and to cry to the Oppressours, or others for pity and help.

Because their Oppressours are too strong for them.
