John Trapp on Micah 7:12

Verſe 12. In that day alſo he ſhall come even to thee from Aſſyria] To thee, Ieruſalem, in the Type, ſhall recourſe be had from all parts, as if thou wert the chief city of the world. (Pliny ſaith, that in his time ſhe was the moſt famous of all the cities of the Eaſt: and Titus himſelf is ſaid to have wept at the laſt deſtruction of it by his ſouldiers, whom he could not reſtrain from firing the Temple) To the new Jeruſalem, the Church of the New Teſtament, in the Antitype: from whence the Goſpel was ſent out to every creature which is under heaven, Col. 1.23. and whereunto people of all ſorts flowed, and many nations came, Mic. 4.1, 2. with higheſt acclamations, moſt vigorous affections, and utmoſt indeavours beſtowing themſelves upon the Lord Chriſt, Act. 2.9. &c. Jeruſalem, in the Hebrew tongue, is of the duall number; in regard of the two parts of the city, the upper and the nether town. Or, (as the Cabaliſts give the reaſon) in regard of a twofold Jeruſalem, the heavenly and the earthly: and the taking away of the earthly, they ſay, was ſignified, by the taking away of the letter jod out of Jeruſhalaijm, 2 Sam. 5.13. But Jeruſalem which is above is free, firme, and full; the deſolate (once ſo) having many more children then ſhe that hath an husband, Gal. 4.26, 27. whom the Lord of Hoſts alſo doth bleſſe, ſaying, (as a Father to them all) Bleſſed be Egypt my people, and Aſſyria the work of my hands, and Iſrael mine inheritance, Eſay 19.23, 24, 25.

and from the fortreſſe, even to the river] i.e. from all bounds and borders of the land, yea of the world (Pſal. 89.12. Tabor and Hermon are put for the Eaſt and Weſt parts of the World) ſhall people come in to the New Jeruſalem, which hath twelve gates: On the Eaſt three gates, on the North three gates, on the South three gates, and on the Weſt three gates, Rev. 21.12, 13.
