Job 16:4

"I too could speak like you": If the circumstances were reversed, Job could certainly fire verbal bullets at them, yet in verse. he seems to indicate that he would try to help them. "He could do far better than they were doing, for he could indeed strengthen people with his words (Job 4:4), and he could offer solace that would ease their pain" (Zuck p. 76). To "shake the head" at someone was another way of mocking someone (Psalms 22:7).
