If we apply this to the state of the Jews after their return out of captivity, it is a prophecy of the increase of their nation after they were settled in their own land. Jerusalem had been in the condition of a wife written childless, or a desolate solitary widow; but now it is promised that the city should be replenished and the country peopled again, that not only the ruins of Jerusalem should be repaired, but the suburbs of it extended on all sides and a great many buildings erected upon new foundations, - that those estates which had for many years been wrongfully held by the Babylonian Gentiles should now return to the right owners. God will again be a husband to them, and the reproach of their captivity, and the small number to which they were then reduced, shall be forgotten. And it is to be observed that, by virtue of the ancient promise made to Abraham of the increase of his seed, when they were restored to God's favour they multiplied greatly. Those that first came out of Babylon were but 42,000 (Ezr 2:64), about a fifteenth part of their number when they came out of Egypt; many came dropping to them afterwards, but we may suppose that to be the greatest number that ever came in a body; and yet above 500 years after, a little before their destruction by the Romans, a calculation was made by the number of the paschal lambs, and the lowest computation by that rule (allowing only ten to a lamb, whereas they might be twenty) made the nation to be nearly three millions. Josephus says, seven and twenty hundred thousand and odd, Jewish War 6.425. But we must apply it to the church of God in general; I mean the kingdom of God among men, God's city in the world, the children of God incorporated. Now observe,

I.The low and languishing state of religion in the world for a long time before Christianity was brought in. It was like one barren, that did not bear, or travail with child, was like one desolate, that had lost husband and children; the church lay in a little compass, and brought forth little fruit. The Jews were indeed by profession married to God, but few proselytes were added to them, the rising generations were unpromising, and serious godliness manifestly lost ground among them. The Gentiles had less religion among them than the Jews; their proselytes were in a dispersion; and the children of God, like the children of a broken, reduced family, were scattered abroad (Joh 11:52), did not appear nor make any figure.

II.Its recovery from this low condition by the preaching of the gospel and the planting of the Christian church.

1.Multitudes were converted from idols to the living God. Those were the church's children that were born again, were partakers of a new and divine nature, by the word. More were the children of the desolate than of the married wife; there were more good people found in the Gentile church (when that was set up) that had long been afar off, and without God in the world, than ever were found in the Jewish church. God's sealed ones out of the tribes of Israel are numbered (Rev 7:4), and they were but a remnant compared with the thousands of Israel; but those of other nations were so many, and crowded in so thickly, and lay so much scattered in all parts, that no man could number them, Isa 54:9. Sometimes more of the power of religion is found in those places and families that have made little show of it, and have enjoyed but little of the means of grace, than in others that have distinguished themselves by a flourishing profession; and then more are the children of the desolate, more the fruits of their righteousness, than those of the married wife; so the last shall be first. Now this is spoken of as matter of great rejoicing to the church, which is called upon to break forth into singing upon this account. The increase of the church is the joy of all its friends and strengthens their hands. The longer the church has lain desolate the greater will the transports of joy be when it begins to recover the ground it has lost and to gain more. Even in heaven, among the angels of God, there is an uncommon joy for a sinner that repents, much more for a nation that does so. If the barren fig-tree at length bring forth fruit, it is well; it shall rejoice, and others with it.

2.The bounds of the church were extended much further than ever before, Isa 54:2, Isa 54:3. (1.) It is here supposed that the present state of the church is a tabernacle state; it dwells in tents, like the heirs of promise of old (Heb 11:9); its dwelling is mean and movable, and of no strength against a storm. The city, the continuing city, is reserved for hereafter. A tent is soon taken down and shifted, so the candlestick of church privileges is soon removed out of its place (Rev 2:5), and, when God pleases, it is as soon fixed elsewhere. (2.) Though it be a tabernacle state, it is sometimes very remarkably a growing state; and, if this family increase, no matter though it be in a tent. Thus it was in the first preaching of the gospel; it was the business of the apostles to disciple all nations, to stretch forth the curtains of the church's habitation, to preach the gospel where Christ had not yet been named (Rom 15:20), to leaven with the gospel those towns and countries that had hitherto been strangers to it, and so to lengthen the cords of this tabernacle, that more might be enclosed, which would make it necessary to strengthen the stakes proportionably, that they might bear the weight of the enlarged curtains. The more numerous the church grows the more cautious she must be to fortify herself against errors and corruptions, and to support her seven pillars, Pro 9:1. (3.) It was a proof of divine power going along with the gospel that in all places it grew and prevailed mightily, Act 19:20. It broke forth, as the breaking forth of waters - on the right hand and on the left, that is, on all hands. The gospel spread itself into all parts of the world; there were eastern and western churches. The church's seed inherited the Gentiles, and the cities that had been desolate (that is, destitute of the knowledge and worship of the true God) came to be inhabited, that is, to have religion set up in them and the name of Christ professed.

3.This was the comfort and honour of the church (Isa 54:4): "Fear not, for thou shalt not be ashamed, as formerly, of the straitness of thy borders, and the fewness of thy children, which thy enemies upbraided thee with, but shalt forget the reproach of thy youth, because there shall be no more ground for that reproach." It was the reproach of the Christian religion, in its youth, that none of the rulers or princes of this world embraced it and that it was entertained and professed by a despicable handful of men; but, after awhile, nations were discipled, the empire became Christian, and then this reproach of its youth was forgotten.

4.This was owing to the relation in which God stood to his church, as her husband (Isa 54:5): Thy maker is thy husband. Believers are said to be married to Christ, that they may bring forth fruit unto God (Rom 7:4); so the church is married to him, that she may bear and bring up a holy seed to God, that shall be accounted to him for a generation. Jesus Christ is the church's Maker, by whom she is formed into a people - her Redeemer, by whom she is brought out of captivity, the bondage of sin, the worst of slaveries. This is he that espoused her to himself; and, (1.) He is the Lord of hosts, who has an irresistible power, an absolute sovereignty, and a universal dominion! Kings who are lords of some hosts, find there are others who are lords of other hosts, as many and mighty as theirs; but God is the Lord of all hosts. (2.) He is the Holy One of Israel, the same that presided in the affairs of the Old Testament church and was the Mediator of the covenant made with it. The promises made to the New Testament Israel are as rich and sure as those made to the Old Testament Israel; for he that is our Redeemer is the Holy One of Israel. (3.) He is and shall be called the Lord of the whole earth, as God, and as Mediator, for he is the heir of all things; but then he shall be called so, when the ends of the earth shall be made to see his salvation, when all the earth shall call him their God and have an interest in him. Long he had been called, in a peculiar manner, the God of Israel; but now, the partition wall between Jew and Gentile being taken down, he shall be called the God of the whole earth even where he has been, as at Athens itself, an unknown God.

For thou shalt forget the shame of thy youth - That is, "The bondage of Egypt: widowhood, the captivity of Babylon." - Secker.

Fear not,.... The fulfilment of these things; however unlikely and unpromising they might seem, yet God was able to perform them; and therefore way should not be given to a fearful, distrustful, and unbelieving heart:

for thou shall not be ashamed; as men are, when disappointed of what they have been hoping for and expecting; but so it should not be with the church, she should not be ashamed of her hope, faith, and confidence; for there would be a performance of all that the Lord had spoken: nor should she be ashamed of her barrenness, which should cease; and of the fewness of her children or converts, which would be many; and of the straitness of the place of her tent or habitation, which would now be enlarged:

neither be thou confounded, for thou shalt not be put to shame; other words made use of to express the same thing, and for the further confirmation of it, that she needed not, and that she should not be put to the blush, or to shame and confusion, on the above accounts:

for thou shalt forget the shame of thy youth; by which may be meant either the small number of converts at the first preaching of the Gospel; or more especially that there were so few of the wise and learned, the rich and noble, that embraced it, with which the first Christians were greatly upbraided; or those persecutions which attended them the three first centuries, which, being now at an end, shall be forgotten:

and shalt not remember the reproach of thy widowhood any more; which signifies much the same as before, the seeming desolate estate of the church upon the death of Christ; when she seemed to be deprived of her husband, and forsaken by him, and left as a widow, and without children, barren and unfruitful; which was reckoned reproachful with the Jews, Luk 1:25.

(Isa 41:10, Isa 41:14).

shame of thy youth--Israel's unfaithfulness as wife of Jehovah, almost from her earliest history.

reproach of widowhood--Israel's punishment in her consequent dismissal from God and barrenness of spiritual children in Babylon and her present dispersion (Isa 54:1; Isa 49:21; Jer 3:24-25; Jer 31:19; Hos 2:2-5).
