2. Jerusalem made easy by the promises of God: "Why dost thou cry out aloud? Let thy griefs and fears be silenced; indulge not thyself in them, for, though things are bad with thee, they shall end well; thy pangs are great, but they are like those of a woman in travail (v. 9), that labours to bring forth (v. 10), the issue of which will be good at last." Jerusalem's pangs are not as dying agonies, but as travailing throes, which after a while will be forgotten, for joy that a child is born into the world. Let the literal Jerusalem comfort herself with this, that, whatever straits she may be reduced to, she shall continue until the coming of the Messiah, for there his kingdom must be first set up, and she shall not be destroyed while that blessing is in her; and when at length she is ploughed as a field, and become heaps (as is threatened, ch. iii. 12), yet her privileges shall be resigned to the spiritual Jerusalem, and in that the promises made to her shall be fulfilled. Let Jerusalem be easy then, for, (1.) Her captivity in Babylon shall have an end, a happy end (v. 10): There shalt thou be delivered, and the Lord shall redeem thee from the hand of thy enemies there. This was done by Cyrus, who acted therein as God's servant; and that deliverance was typical of our redemption by Jesus Christ, and the release from our spiritual bondage which is proclaimed in the everlasting gospel, that acceptable year of the Lord, in which Christ himself preached liberty to the captives, and the opening of the prison to those that were bound, Luke iv. 18, 19. (2.) The designs of her enemies against her afterwards shall be baffled, nay, they shall turn upon themselves, v. 12, 13. They promise themselves a day of it, but it shall prove God's day. They are gathered against Zion, to destroy it, but it shall prove to their own destruction, which Israel and Israel's God shall have the glory of. [1.] Their coming together against Zion shall be the occasion of their ruin. They associate themselves, and gird themselves, that they may break Jerusalem in pieces, but it will prove that they shall be broken in pieces, Isa. viii. 9. They know not the thoughts of the Lord. When they are gathering together, and Providence favours them in it, they little think what God is designing by it, nor do they understand his counsel; they know what they aim at in coming together, but they know not what God aims at in bringing them together; they aim at Zion's ruin, but God aims at theirs. Note, When men are made use of as instruments of Providence in accomplishing its purposes it is very common for them to intend one thing and for God to intend quite the contrary. The king of Assyria is to be a rod in God's hand for the correction of his people, in order to their reformation; howbeit he means not so, nor does his heart think so, Isa. x. 7. And thus it is here; the nations are gathered against Zion, as soldiers into the field, but God gathers them as sheaves into the floor, to be beaten to pieces; and they could not have been so easily, so effectually, destroyed, if they had not gathered together against Zion. Note, The designs of enemies for the ruin of the church often prove ruining to themselves; and thereby they prepare themselves for destruction and put themselves in the way of it; they are snared in the work of their own hands. [2.] Zion shall have the honour of being victorious over them, v. 13. When they are gathered as sheaves into the floor, to be trodden down, as the corn then was by the oxen, then, "Arise, and thresh, O daughter of Zion! instead of fearing them, and fleeing from them, boldly set upon them, and take the opportunity Providence favours thee with of trampling upon them. Plead not thy own weakness, and that thou art not a match for so many confederated enemies; God will make thy horn iron, to push them down, and thy hoofs brass, to tread upon them when they are down; and thus thou shalt beat in pieces many people, that have long been beating thee in pieces." Thus, when God pleases, the daughter of Babylon is made a threshing floor (it is time to thresh her, Jer. li. 33), and the worm Jacob is made a threshing instrument, with which God will thresh the mountains, and make them as chaff, Isa. xli. 14, 15. How strangely, how happily, are the tables turned, since Jacob was the threshing-floor and Babylon the threshing instrument! Isa. xxi. 10. Note, When God has conquering work for his people to do he will furnish them with strength and ability for it, will make the horn iron and the hoofs brass; and, when he does so, they must exert the power he gives them, and execute the commission; even the daughter of Zion must arise, and thresh. [3.] The glory of the victory shall redound to God. Zion shall thresh these sheaves in the floor, but the corn threshed out shall be a meat-offering at God's altar: I will consecrate their gain unto the Lord (that is, I will have it consecrated) and their substance unto the Lord of the whole earth. The spoils gained by Zion's victory shall be brought into the sanctuary, and devoted to God, either in part, as those of Midian (Num. xxxi. 28), or in whole, as those of Jericho, Josh. vi. 17. God is Jehovah, the fountain of being; he is the Lord of the whole earth, the fountain of power; and therefore he needs not any of our gain or substance, but may challenge and demand it all if he please; and with ourselves we must devote all we have to his honour, to be employed as he directs. Thus far all we have must have holiness to the Lord written upon it, all our gain and substance must be consecrated to the Lord of the whole earth, Isa. xxiii. 18. And extraordinary successes call for extraordinary acknowledgments, whether they be of spoils in war or gains in trade. It is God that gives us power to get wealth, which way soever it is honestly got, and therefore he must be honoured with what we get. Some make all this to point at the defeat of Sennacherib when he besieged Jerusalem, others to the destruction of Babylon, others to the successes of the Maccabees; but the learned Dr. Pocock and others think it had its full accomplishment in the spiritual victories obtained by the gospel of Christ over the powers of darkness that fought against it. The nations thought to ruin Christianity in its infancy, but it was victorious over them; those that persisted in their enmity were broken to pieces (Matt. xxi. 44), particularly the Jewish nation; but multitudes by divine grace were gained to the church, and they and their substance were consecrated to the Lord Jesus, the Lord of the whole earth.
