Ver. 5. For in mercy (or piety) ſhall the throne be eſtabliſhed] Hezekiah's throne ſhall, (but eſpecially Chriſts) from whom ye may once have occaſion to borrow that mercy which now you are called upon to lend to thoſe outcaſts of Iſrael.

And he ſhall ſet upon it] i. e. He ſhall make it his buſineſs to relieve and right his people.

And ſeeking judgment] Making inquiſition after wrongs of ſuch as dare not complain. The Grand Signior, they ſay, ſhew himſelf on purpoſe weekly abroad, for the receiving the poors petitions, and puniſhing the Grandees of his Court by whom they are oppreſſed: whence alſo he ſtileth himſelf Awlem Penawh, i. e. the worlds Refuge.

And haſtening juſtice] Diſpatching and diſpeeding cauſes.
