Isaiah 27:13

And it shall come to pass in that day,.... When the Lord is about to do the above things, and in order to it. The Talmudists k apply this text to the world to come, or times of the Messiah, when the ten tribes shall be returned:

[that] the great trumpet shall be blown; meaning not the edict or proclamation of Cyrus, but the ministration of the Gospel, called a "trumpet", in allusion to those that were ordered by Moses to be made for the congregation of Israel, Numbers 10:1, or to the jubilee trumpet, Leviticus 25:9 or with respect to any trumpet giving a musical sound; the Gospel being a joyful sound, a sound of love, grace, and mercy through Christ, of peace, pardon, righteousness, and salvation by him; and which may be called a "great" one, the author of it, God, being great; and it is the effect of great love, and the produce of great wisdom; it proclaims and publishes great things, great promises, great truths, and a great salvation; it gives a great sound, which has and will again go into all the world, and reach to the ends of the earth; and has been, and will be, attended with great power; the "blowing" of it intends the ministry of the word, which to perform aright requires ability and skill; and here it respects the ministration of it in the latter day, when this Gospel trumpet will be blown more clearly, and without any jar, discord, and confusion; and more loudly, openly, and publicly; and more effectually, and to greater purpose:

and they shall come which were ready to perish in the land of Assyria, and the outcasts in the land of Egypt; all mankind are in a perishing condition, but all are not sensible of it; some are, and they become so through the preaching of the word, attended with the power and Spirit of God; whereby they are convinced of sin, and of their lost estate by nature; their consciences are loaded with guilt, their souls are filled with a sense of wrath; they have a sight of sin, but not of a Saviour from it, or of the pardon of it; they have a view of a broken law, which curses and condemns, and of injured justice brandishing its sword against them, but see they have no righteousness to satisfy one or the other; and find themselves in a starving condition, ready to perish with hunger; and are like the wretched infant "cast out" into the open field, to the "loathing" of its person: and these now, whether in Assyria or in Egypt, or wherever they are, the Gospel trumpet will reach them, and encourage them to come; and powerful and efficacious grace accompanying it will engage and cause them to "come" first to Christ as poor perishing sinners, and venture their souls on him for life and salvation; they shall come to him in a way of believing, for pardon, cleansing, rest, food, righteousness, and life; and then they shall come to his churches, and give up themselves unto them, to walk with them:

and shall worship the Lord in the holy mount at Jerusalem; in the Gospel church, signified frequently by Mount Zion and Jerusalem; see

Hebrews 12:22 where the Jews shall come, when converted, and join themselves, and worship God internally and externally, in spirit and in truth: and it may be true of Mount Zion, and of Jerusalem, in a literal sense, which will be rebuilt, and inhabited by the Jews, and become a place of divine worship.
