John Trapp on Jeremiah 30:21

Ver. 21. And their Nobles ſhall be of themſelves] Forreiners ſhall no more domineer over them, but they ſhall have Governours of their own Nation, who ſhall be more tender of them, and careful of their good. Some apply all this (and well they may) to Jeſus Chriſt who is here called Magnificus, & Dominator, Chriſtus Fortis ille & G[illegible: 1 letter]gat eſt; Oecol. his Magnificent or honourable One, and his Ruler: who alſo is one of them, and proceedeth from amongſt them. See Deut. 18.18.

And I will cauſe him to draw near, and he ſhall approach unto me] Either as God, coequal and coeſſential with me; or as Mediatour: and ſo he ſhall approach unto me by the hypoſtatical union, (in reſpect of which he came the neareſt unto God of any that ever was or could) and by the execution of his Prieſtly office, wherein he intercedeth for my people and reconcileth them unto me.

For who is this that engaged his heart] Who but my Son Chriſt durſt do it, or was fit to do it? he is a ſuper-excellent perſon, as is imported by this Mi-hu-ze, Who this he?
