4. Though Jerusalem shall be desolate and forsaken for a time, yet there will come a day when its scattered friends shall resort to it again out of all the countries whither they were dispersed (v. 12, 13); though the body of the nation is abandoned as a people of no understanding, yet those that are indeed children of Israel shall be gathered together again, as the sheep of the flock when the shepherds that scattered them are reckoned with, Ezek. xxxiv. 10-19. Now observe concerning these scattered Israelites, (1.) Whence they shall be fetched: The Lord shall beat them off as fruit from the tree, or beat them out as corn out of the ear. He shall find them out, and separate them from those among whom they dwelt, and with whom they seemed to be incorporated, from the channel of the river Euphrates north-east, unto Nile, the stream of Egypt, which lay south-west—those that were driven into the land of Assyria, and were captives there in the land of their enemies, where they were ready to perish for want of necessaries, and ready to despair of deliverance—and those that were outcasts in the land of Egypt, whither many of those that were left behind, after the captivity in Babylon, went, contrary to God's express command (Jer. xliii. 6, 7), and there lived as outcasts: God has mercy in store for them all, and will make it to appear that, though they are cast out, they are not cast off. (2.) In what manner they shall be brought back: "You shall be gathered one by one, not in multitudes, not in troops forcing your way; but silently, and as it were by stealth, dropping in, first one, and then another." This intimates that the remnant that shall be saved consists but of few, and those saved with difficulty, and so as by fire, scarcely saved; they shall not come for company, but as God shall stir up every man's spirit. (3.) By what means they shall be gathered together: The great trumpet shall be blown, and then they shall come. Cyrus's proclamation of liberty to the captives is this great trumpet, which awakened the Jews that were asleep in their thraldom to bestir themselves; it was like the sounding of the jubilee-trumpet, which published the year of release. This is applicable both to the preaching of the gospel, by which sinners are gathered in to the grace of God, such as were outcasts and ready to perish (those that were afar off are made nigh; the gospel proclaims the acceptable year of the Lord), and also to the archangel's trumpet at the last day, by which saints shall be gathered to the glory of God, that lay as outcasts in their graves. (4.) For what end they shall be gathered together: To worship the Lord in the holy mount at Jerusalem. When the captives rallied again, and returned to their own land, the chief thing they had their eye upon, and the first thing they applied themselves to, was the worship of God. The holy temple was in ruins, but they had the holy mount, the place of the altar, Gen. xiii. 4. Liberty to worship God is the most valuable and desirable liberty; and, after restraints and dispersions, a free access to his house should be more welcome to us than a free access to our own houses. Those that are gathered by the sounding of the gospel trumpet are brought in to worship God and added to the church; and the great trumpet of all will gather the saints together, to serve God day and night in his temple.
