II. Here is his wonderful forwardness to do good for Israel, which appears in this, that he will qualify them to receive the good he designs for them (v. 10, 11): They shall walk after the Lord. This respects the same favour with that (ch. iii. 5), They shall return, and seek the Lord their God; it is spoken of the ten tribes, and had its accomplishment, in part, in the return of some of them with those of the two tribes in Ezra's time; but it had its more full accomplishment in God's spiritual Israel, the gospel-church, brought together and incorporated by the gospel of Christ. The ancient Jews referred it to the time of the Messiah; the learned Dr. Pocock looks upon it as a prophecy of Christ's coming to preach the gospel to the dispersed children of Israel, the children of God that were scattered abroad. And then observe, 1. How they were to be called and brought together: The Lord shall roar like a lion. The word of the Lord (so says the Chaldee) shall be as a lion that roars. Christ is called the lion of the tribe of Judah, and his gospel, in the beginning of it, was the voice of one crying in the wilderness. When Christ cried with a loud voice it was as when a lion roared, Rev. x. 3. The voice of the gospel was heard afar, as the roaring of a lion, and it was a mighty voice. See Joel iii. 16. 2. What impression this call should make upon them, such an impression as the roaring of a lion makes upon all the beasts of the forest: When he shall roar then the children shall tremble. See Amos iii. 8, The lion has roared; the Lord God has spoken; and then who will not fear? When those whose hearts the gospel reached trembled, and were astonished, and cried out, What shall we do?—when they were by it put upon working out their salvation, and worshipping God with fear and trembling, then this promise was fulfilled. The children shall tremble from the west. The dispersed Jews were carried eastward, to Assyria and Babylon, and those that returned came from the east; therefore this seems to have reference to the calling of the Gentiles that lay westward from Canaan, for that way especially the gospel spread. They shall tremble; they shall move and come with trembling, with care and haste, from the west, from the nations that lay that way, to the mountain of the Lord (Isa. ii. 3), to the gospel-Jerusalem, upon hearing the alarm of the gospel. The apostle speaks of mighty signs and wonders that were wrought by the preaching of the gospel from Jerusalem round about to Illyricum, Rom. xv. 19. Then the children trembled from the west. And, whereas Israel after the flesh was dispersed in Egypt and Assyria, it is promised that they shall be effectually summoned thence (v. 11): They shall tremble; they shall come trembling, and with all haste, as a bird upon the wing, out of Egypt, and as a dove out of the land of Assyria; a dove is noted for swift and constant flight, especially when she flies to her windows, which the flocking of Jews and Gentiles to the church is here compared to, as it is Isa. lx. 8. Wherever those are that belong to the election of grace—east, west, north, or south—they shall hear the joyful sound, and be wrought upon by it; those of Egypt and Assyria shall come together; those that lay most remote from each other shall meet in Christ, and be incorporated in the church. Of the uniting of Egypt and Assyria, it was prophesied, Isa. xix. 23. 3. What effect these impressions should have upon them. Being moved with fear, they shall flee to the ark: They shall walk after the Lord, after the service of the Lord (so the Chaldee); they shall take the Lord Christ for their leader and commander; they shall enlist themselves under him as the captain of their salvation, and give up themselves to the direction of the Spirit as their guide by the word; they shall leave all to follow Christ, as becomes disciples. Note, Our holy trembling at the word of Christ will draw us to him, not drive us from him. When he roars like a lion the slaves tremble and flee from him, the children tremble and flee to him. 4. What entertainment they shall meet with at their return (v. 11): I will place them in their houses (all those that come at the gospel-call shall have a place and a name in the gospel-church, in the particular churches which are their houses, to which they pertain; they shall dwell in God, and be at home in him, both easy and safe, as a man in his own house; they shall have mansions, for there are many in our Father's house), in his tabernacle on earth and his temple in heaven, in everlasting habitations, which may be called their houses, for they are the lot they shall stand in at the end of the days.
