Jamieson, Fausset & Brown

my sighing cometh before I eat--that is, prevents my eating [UMBREIT]; or, conscious that the effort to eat brought on the disease, Job must sigh before eating [ROSENMULLER]; or, sighing takes the place of good (Psa 42:3) [GOOD]. But the first explanation accords best with the text. my roarings are poured out like the waters--an image from the rushing sound of water streaming.
