John Trapp on Job 13:18

Verſe 18. Behold, now I have ordered my cauſe] Heb. my judgment: Hee had ſpoken before of his Declaration, which is conceived to be a Law-term; for in lawſuits, the Plaintiffe putteth in a declaration of his grievance. Job had his declaration ready drawn, and craved audience: he asketh afterwards, Who will plead with me? and here in the like language he telleth us, that he had ordered his cauſe, he had marſhalled and methodized his arguments, he had ſet and ſtated the controverſie. Lo, here I ſtand ready prepared to plead, and am confident I ſhall prevail.

I know that I ſhall be juſtified] That is, I am perſwaded, or I am ſure (as Rom. 8.38.) I believe and I know, as John 6.59. ſc. with a fiducial knowledg, that I ſhall be juſtified, ſc. from my ſins, by Chriſts righteouſneſſe imputed (yea, that I am ſo already; and that for ever: for Peccata non redeunt, diſcharges in juſtification are not repealed or called in again) and that I ſhall depart from Gods bar acquitted in this particular controverſie. And ſo he did; for God juſtified Job, and reproved his three friends, chap. 42.
