John Trapp on Jeremiah 31:12

Ver. 12. Therefore they ſhall come and ſing in the height of Zion] i. e. In the Temple ſhall they celebrate that ſingular mercy, in the Congregation of the faithful.

And ſhall flow together] i. e. Flock together by troops and caravans: flock thither by ſholes.

To the goodneſſe of the Lord] Or, to the goods of the Lord, ſuch as here inſtanced, wheat, wine and oyl; whereby alſo better things are figured: a confluence of inward and outward mercies is here aſſured the Saints.

And their ſoul ſhall be as a watered garden] Where every good thing comes forward amain: mens foecundata est rore coeleſti. See Iſa. 58.11.

And they ſhall not ſorrow any more at all] As thoſe do who have not this contented godlineſſe, but ſerve divers luſts, to their great vexation.
