Job 15:9

What knowest thou that we know not?.... Which are pretty near the words of Job to his friends, Job 12:3; and to the same sense is what follows:

What knowest thou that we know not? - What pretensions or claims to wisdom have you which we have not? We have had, at least, equal advantages, and may be presumed to know as much as you.

Eliphaz here falls very foul upon Job, because he contradicted what he and his colleagues had said, and did not acquiesce in it and applaud it, as they expected. Proud people are apt thus to take it…

Abandoning irony Eliphaz comes to the facts, which hardly bear out Job's pretensions. His words recall those of Job, ch. Job 12:3; Job 13:2.
