Albert Barnes Commentary Job 35:4

"I will answer thee, And thy companions with thee." — Job 35:4 (ASV)

I will answer you - Margin, “return to you words.” Elihu meant to explain this more fully than it had been done by the friends of Job, and to show where Job was in error.

And your companions with you - Eliphaz, in (Job 22:2), had taken up the same inquiry and proposed to discuss the subject, but he had immediately gone into severe charges against Job and been drawn into language of harsh accusation, instead of making the matter clear, and Elihu now proposes to state just how it is and to remove Job's objections. It may be doubted, however, whether he was much more successful than Eliphaz had been. The doctrine of the future state, as it is revealed by Christianity, was necessary to enable these speakers to comprehend and explain this subject.
