John Trapp on Job 12:18

Verſe 18. He looſeth the bonds of Kings] He degradeth them, taking away all command and authority from them, which is the bond that bindeth the people to obedience and ſubjection; Job 30.11. Iſai. 45.1, 5. as our Henry the third,Daniel. who was called Regni dilapidator, ill beloved of his people, and far a leſs King (ſaith the Chronicler) by ſtriving to be more then he was: the juſt reward of violations.

And gardeth their loins with a girdle] With a rope, ſay the Vulgar: he brings them from the throne to the priſon: he layeth affliction upon their loynes,Val. Max Chriſt. pag. 267. as Pſalm 66.11. An inſtance hereof (beſide the late King, and Corradinus King of Germany likewiſe beheaded at Naples) we had here in Richard the ſecond, brought forth in a royal robe to be depoſed, and then hunger-ſtarved in priſon: as alſo in Henry the ſixth, who having been the moſt potent Monarch for dominions that ever England had, was afterwards (when depoſed) not the Maſter of a mole-hill, nor owner of his own liberty, but baffled and beaten by every baſe fellow. Some Interpreters make the ſenſe of this to be thus; God ſometimes looſeth the bonds, into which Princes are brought, and advanceth them again to kingly dignity, the enſign whereof, was of old a precious girdle. So it befell Manaſſeh, Nebuchadnezzar, Jehoiakins, reſtored and honoured againe as a king, by Evilmerodach, 2 Kings 25.28 Hiſtorians write, that Nebuchadnezzar was ſo offended with his ſon and ſucceſſor Evilmerodach, as he caſt him into priſon, and that in priſon he and Jehoiakim became acquainted together, whence his advancement afterwards.
