Jamieson, Fausset & Brown

magnify, &c.--Speak proudly (Oba 1:12; Eze 35:13). against me--emphatically repeated (Psa 38:16). plead . . . reproach--English Version makes this part of the protasis, "if" being understood, and the apodosis beginning at Job 19:6. Better with UMBREIT, If ye would become great heroes against me in truth, ye must prove (evince) against me my guilt, or shame, which you assert. In the English Version "reproach" will mean Job's calamities, which they "pleaded" against him as a "reproach," or proof of guilt.
