John Trapp on Job 12:21

Verſe 21. He poureth contempt upon Princes] Or Nobles, or Gentlemen, which are, or ſhould be free, bounteous, munificent benefactors: if they be not Nedibim, [non-Latin text not transcribed] but Nebalim, liberal, but churliſh, (ſee theſe oppoſed Iſa. 32.5.) it is juſt in God to pour contempt, to lay abundance of ſhame and ſcorn upon them, as ſordid, penny-fathers, ignoble, Euclio's, poor-ſpirited men, the baſe brood, or rather, blot of their better fore-fathers. Of out Edward the ſecond it is chronicled, that never was Prince received with greater love and opinion of all then he; or never any that ſooner loſt it; for his very firſt action in recalling his minion Pierce Gaveſton, Daniel. diſcovered an head-ſtrong wilfulneſſe, that was uncounſellable: hence he was ſlighted by his ſubjects, purſued by his wife and ſon, and at length cruelly murthered. Mercer obſerveth, that David hath the ſelf-ſame words, Pſalm 107.40. that are found here, and verſe 24. Neither need we wonder, ſith they both ſpake by the ſame ſpirit.

And weakneth the ſtrength of the mighty] Heb. He ſlackneth the girdle of the impetuous, that like ſtrong ſtreams in narrow ſtraits, bear down all before them. So do Souldiers in warre; ſee 2 Sam. 22.16. Job 6.15. But God can looſe their girdles (or belts, which bind their garments, and buckle their armour cloſe to them) he can diſpirit them, and make them feeble and faint-hearted, as he did Samſon, and thoſe Aſſyrians Pſalm 76.5, 6. By this whole diſcourſe of Job it appeareth, that he had very diligently obſerved Gods providence, and way of adminiſtration in the ſeveral ranks of men, and alterations of common-wealths; whereby he had learned ſecretly to admire and adore Gods judgments, which thing we ought alſo ſemblably to do.
