And it shall come to pass in that day, that the great trumpet shall be {n} blown, and they shall come who were ready to perish in the land of Assyria, and the outcasts in the land of Egypt, and shall worship the LORD on the holy mount at Jerusalem.

(n) In the time of Cyrus, by whom they would be delivered: but this was chiefly accomplished under Christ.

Wesley's Notes

27:13 Trumpet - God shall summon them altogether by sound of trumpet, by an eminent call of his providence. He alludes to the custom of calling the Israelites together with trumpets.

Jamieson-Fausset-Brown Bible Commentary

13. great trumpet-image from the trumpets blown on the first day of the seventh month to summon the people to a holy convocation (Le 23:24). Antitypically, the gospel trumpet (Re 11:15; 14:6) which the Jews shall hearken to in the last days (Zec 12:10; 13:1). As the passover in the first month answers to Christ's crucifixion, so the day of atonement and the idea of "salvation" connected with the feast of tabernacles in the same seventh month, answer to the crowning of "redemption" at His second coming; therefore redemption is put last in 1Co 1:30.

Assyria-whither the ten tribes had been carried; Babylonia is mainly meant, to which Assyria at that time belonged; the two tribes were restored, and some of the ten accompanied them. However, "Assyria" is designedly used to point ultimately to the future restoration of the ten fully, never yet accomplished (Jer 3:18).

Egypt-whither many had fled at the Babylonish captivity (Jer 41:17, 18). Compare as to the future restoration, Isa 11:11, 12, 16; 51:9-16 ("Rahab" being Egypt).

Matthew Henry's Concise Commentary

27:6-13 In the days of the gospel, the latter days, the gospel church shall be more firmly fixed than the Jewish church, and shall spread further. May our souls be continually watered and kept, that we may abound in the fruits of the Spirit, in all goodness, righteousness, and truth. The Jews yet are kept a separate and a numerous people; they have not been rooted out as those who slew them. The condition of that nation, through so many ages, forms a certain proof of the Divine origin of the Scriptures; and the Jews live amongst us, a continued warning against sin. But though winds are ever so rough, ever so high, God can say to them, Peace, be still. And though God will afflict his people, yet he will make their afflictions to work for the good of their souls. According to this promise, since the captivity in Babylon, no people have shown such hatred to idols and idolatry as the Jews. And to all God's people, the design of affliction is to part between them and sin. The affliction has done us good, when we keep at a distance from the occasions of sin, and use care that we may not be tempted to it. Jerusalem had been defended by grace and the Divine protection; but when God withdrew, she was left like a wilderness. This has awfully come to pass. And this is a figure of the deplorable state of the vineyard, the church, when it brought forth wild grapes. Sinners flatter themselves they shall not be dealt with severely, because God is merciful, and is their Maker. We see how weak those pleas will be. Verses 12,13, seem to predict the restoration of the Jews after the Babylonish captivity, and their recovery from their present dispersion. This is further applicable to the preaching of the gospel, by which sinners are gathered into the grace of God; the gospel proclaims the acceptable year of the Lord. Those gathered by the sounding of the gospel trumpet, are brought in to worship God, and added to the church; and the last trumpet will gather the saints together.
