Jeremiah 23:7,8 - Joseph Benson’s Commentary on the Old and New Testaments

Therefore, behold, the days come, saith the Lord Here the prophet proceeds to fore-tel one very important, although remote, consequence of God's raising up the righteous branch to David, namely, the great salvation which should thereby come to the Jews in the latter days of their state, which should be so illustrious as far to outshine their deliverance out of Egypt. That they shall no more say, The Lord liveth, &c. These words we had before, Jeremiah 16:14-15, where see the note. But here the passage seems to point more plainly than it did there to the days of the Messiah, and to compare, not so much the two deliverances themselves, giving the preference to the latter, as the two states to which the church should grow after those deliverances. About four hundred and eighty years after they were come out of Egypt, Solomon's temple was built, 1 Kings 6:1; and at that time that nation, which was so wonderfully brought out of Egypt, was gradually arrived to its height. And four hundred and ninety years (seventy weeks) after they came out of Babylon, Messiah the Prince set up the gospel temple, which was the greatest glory of that nation that was so wonderfully brought out of Babylon: see Daniel 9:24-25. Now the spiritual glory of the second period of that nation, especially as transferred to the gospel church, is much more admirable and illustrious than all the temporal glory of the first period of it, in the days of Solomon; for that was no glory, compared with the glory which excelleth. Add to this, the prophet, it seems, also foretels a second gathering of the Jews from their dispersions, namely, one that should take place after the coming of the Messiah, and the ruin of their city and country by the Romans, and therefore yet future. Now this work of God, whenever it shall be effected, including, as it undoubtedly will, their conversion to Christianity, and perhaps, also, their restoration to their own land, will assuredly appear so wonderful as greatly to outshine every former deliverance wrought for that people, and therefore may well put every other out of remembrance. St. Paul calls this restoration of them, life from the dead, (Romans 9:25,) meaning that it would be a miracle as surprising as the resurrection of a multitude of dead bodies.
