Jeremiah 31:40

We now see the design of the Prophet: after having spoken of the return of the people, he adds that the city would again become splendid and large, as it had been; for the land continued in a state of disorder until the restoration of the city, as God had there chosen a habitation for himself. And as the Temple had been built there, it behoved the Israelites, wherever they dwelt, ever to direct their eyes to the Temple and the sanctuary of God, that they might live under his protection. Except, then, the city had been built again, the goodness of God could not have been really enjoyed; for a sort of desolation would have otherwise ever presented itself to the eyes of the people, as the city was as it were the banner under which God protected them. This then is the reason why the Prophet expressly announced this prophecy respecting the future restoration of the city.

Now, when he says that the city would be built to Jehovah, he intimates what was especially expected by the Jews, that that city would again be holy; for if it only flourished in wealth and power like other cities, it would have been but a small comfort to the Israelites. But he points out here a difference between Jerusalem and all heathen cities; for God was, as it were, the architect of that city, as it is said in the Psalms,

“He himself founded it,” (Psalm 87:5)

and further,

“His foundations are on the holy mountains,”

and this ought to be understood of himself. (Psalm 87:1) The meaning is, that God would again care for that city, as the Temple would become as it were his royal throne and earthly sanctuary. At the same time when the Prophet affirms that the extent of the city would not be less than it had been, we see that this prophecy must necessarily be referred to the kingdom of Christ: for though Jerusalem before Christ’s coming was eminent and surrounded by a triple wall, and though it was celebrated through all the East, as even heathen writers say that it excelled every other city, yet it was never accomplished, that the city flourished as under David and Solomon. We must then necessarily come to the spiritual state of the city, and explain the promise as the grace which came through Christ.

But we must especially notice what is said, that it would be holiness to Jehovah, and also that no ruin or destruction would be dreaded any more. Had the condition of the elect people been the same as that of other nations, the promise of restoration would have been small and of no great moment; for it would have been better for them to dwell in exile where they inhabited a pleasant and fertile country. But the Prophet here commends a privilege with which God had favored the children of Abraham above all other nations, when he adopted them as his peculiar people. There is however to be understood an implied contrast between the profanation which then prevailed, and the sanctification which is here promised. The Jews had so polluted the land that it differed nothing from other countries; and God, as Ezekiel says, had thence migrated, (Ezekiel 8:6) and we know that the Temple was called by the prophets the den of robbers, (Jeremiah 7:11) and that the city was also compared to Sodom and Gomorrah. (Isaiah 1:10) Hence the Prophet here promises that the city, with its whole vicinity, would be holy to God, because God would cleanse it from all the defilements by which it had been polluted: and he also claims this as his own work, for to sanctify is a work peculiar to himself.

The promise of perpetual favor is added, as it is also done by Zechariah; for it would not be sufficient to have God’s mercy promised to us for a short time, except its perpetuity were secured. The Prophet then promises now that the course of God’s benefits would be permanent;. The city indeed was again destroyed by Titus, and at length wholly demolished by Adrian; but this fact does not militate against this promise; for as we have said, God gave some taste of his favor in the external aspect of the city until Christ came; but after Christ was manifested, the heavenly Jerusalem became the object to be sought, for all the types and shadows then ceased. The perpetuity then of which the Prophet speaks, is that which corresponds with the character of Christ’s kingdom, and is therefore spiritual. Moreover, this passage teaches us that the Church will be perpetual, and that though God may permit it to be terribly shaken and tossed here and there, there will yet be ever some seed remaining, as long as the sun and the moon shall shine in the heavens, and the order of nature shall continue; so that all the elements, everything we see with our eyes, bear evidence to the perpetuity of the Church, even that it will ever continue: for though Satan and all the world daily threaten its ruin, yet the Lord will in a wonderful manner preserve it to the end, so that it will never perish. This is the import of the passage. Another prophecy follows.
