{7} For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the {f} desolate hath many more children than she which hath an husband.

(7) He shows that in this allegory he has followed the steps of Isaiah, who foretold that the Church should be made and consist of the children of barren Sara, that is to say, of those who should be made Ahraham's children by faith, and this only spiritually, rather than of fruitful Hagar, even then foretelling the casting off of the Jews, and the calling of the Gentiles.

(f) She that is destroyed and laid waste.

People's New Testament

4:27 For it is written. See Isa 54:1. In that connection the prophet speaks of the Babylonian bondage, of Abraham and Sarah, and then of the deliverance, looking onward to the glorious deliverance in Christ. Chapter 53 is all concerning Christ, and chapter 54 speaks of the great deliverance.

Thou barren that bearest not. Sarah, the type of the church, long childless.

The desolate hath many more children than she which hath an husband. Sarah, or rather the church, that has more children by far than the children of the old covenant.

Wesley's Notes

4:27 For it is written - Those words in the primary sense promise a flourishing state to Judea, after its desolation by the Chaldeans. Rejoice. thou barren, that bearest not - Ye heathen nations, who, like a barren woman, were destitute, for many ages, of a seed to serve the Lord. Break forth and cry aloud for joy, thou that, in former time, travailedst not: for the desolate hath many more children than she that hath an husband - For ye that were so long utterly desolate shall at length bear more children than the Jewish church, which was of old espoused to God. Isa 54:1.

Jamieson-Fausset-Brown Bible Commentary

27. (Isa 54:1).

thou barren-Jerusalem above: the spiritual Church of the Gospel, the fruit of "the promise," answering to Sarah, who bore not "after the flesh": as contrasted with the law, answering to Hagar, who was fruitful in the ordinary course of nature. Isaiah speaks primarily of Israel's restoration after her long-continued calamities; but his language is framed by the Holy Spirit so as to reach beyond this to the spiritual Zion: including not only the Jews, the natural descendants of Abraham and children of the law, but also the Gentiles. The spiritual Jerusalem is regarded as "barren" while the law trammeled Israel, for she then had no spiritual children of the Gentiles.

break forth-into crying.

cry-shout for joy.

many more-Translate as Greek, "Many are the children of the desolate (the New Testament Church made up in the greater part from the Gentiles, who once had not the promise, and so was destitute of God as her husband), more than of her which hath an (Greek, 'THE') husband (the Jewish Church having God for her husband, Isa 54:5; Jer 2:2)." Numerous as were the children of the legal covenant, those of the Gospel covenant are more so. The force of the Greek article is, "Her who has THE husband of which the other is destitute."

Matthew Henry's Concise Commentary

4:21-27 The difference between believers who rested in Christ only, and those who trusted in the law, is explained by the histories of Isaac and Ishmael. These things are an allegory, wherein, beside the literal and historical sense of the words, the Spirit of God points out something further. Hagar and Sarah were apt emblems of the two different dispensations of the covenant. The heavenly Jerusalem, the true church from above, represented by Sarah, is in a state of freedom, and is the mother of all believers, who are born of the Holy Spirit. They were by regeneration and true faith, made a part of the true seed of Abraham, according to the promise made to him.

Matthew Henry's Whole Bible Commentary

Verses 21-31

In these verses the apostle illustrates the difference between believers who rested in Christ only and those judaizers who trusted in the law, by a comparison taken from the story of Isaac and Ishmael. This he introduces in such a manner as was proper to strike and impress their minds, and to convince them of their great weakness in departing from the truth, and suffering themselves to be deprived of the liberty of the gospel: Tell me, says he, you that desire to be under the law, do you not hear the law? He takes it for granted that they did hear the law, for among the Jews it was wont to be read in their public assemblies every sabbath day; and, since they were so very fond of being under it, he would have them duly to consider what is written therein (referring to what is recorded Gen. 16 and 21), for, if they would do this, they might soon see how little reason they had to trust in it. And here, 1. He sets before them the history itself (v. 22, 23): For it is written, Abraham had two sons, etc. Here he represents the different state and condition of these two sons of Abraham-that the one, Ishmael, was by a bond-maid, and the other, Isaac, by a free-woman; and that whereas the former was born after the flesh, or by the ordinary course of nature, the other was by promise, when in the course of nature there was no reason to expect that Sarah should have a son. 2. He acquaints them with the meaning and design of this history, or the use which he intended to make of it (v. 24-27): These things, says he, are an allegory, wherein, besides the literal and historical sense of the words, the Spirit of God might design to signify something further to us, and that was, That these two, Agar and Sarah, are the two covenants, or were intended to typify and prefigure the two different dispensations of the covenant. The former, Agar, represented that which was given from mount Sinai, and which gendereth to bondage, which, though it was a dispensation of grace, yet, in comparison of the gospel state, was a dispensation of bondage, and became more so to the Jews, through their mistake of the design of it, and expecting to be justified by the works of it. For this Agar is mount Sinai in Arabia (mount Sinai was then called Agar by the Arabians), and it answereth to Jerusalem which now is, and is in bondage with her children; that is, it justly represents the present state of the Jews, who, continuing in their infidelity and adhering to that covenant, are still in bondage with their children. But the other, Sarah, was intended to prefigure Jerusalem which is above, or the state of Christians under the new and better dispensation of the covenant, which is free both from the curse of the moral and the bondage of the ceremonial law, and is the mother of us all-a state into which all, both Jews and Gentiles, are admitted, upon their believing in Christ. And to this greater freedom and enlargement of the church under the gospel dispensation, which was typified by Sarah the mother of the promised seed, the apostle refers that of the prophet, Isa. 54:1, where it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not; for the desolate hath many more children than she who hath a husband. 3. He applies the history thus explained to the present case (v. 28); Now we, brethren, says he, as Isaac was, are the children of the promise. We Christians, who have accepted Christ, and rely upon him, and look for justification and salvation by him alone, as hereby we become the spiritual, though we are not the natural, seed of Abraham, so we are entitled to the promised inheritance and interested in the blessings of it. But lest these Christians should be stumbled at the opposition they might meet with from the Jews, who were so tenacious of their law as to be ready to persecute those who would not submit to it, he tells them that this was no more than what was pointed to in the type; for as then he that was born after the flesh persecuted him that was born after the Spirit, they must expect it would be so now. But, for their comfort in this case, he desires them to consider what the scripture saith (Gen. 21:10), Cast out the bond-woman and her son, for the son of the bond-woman shall not be heir with the son of the free-woman. Though the judaizers should persecute and hate them, yet the issue would be that Judaism would sink, and wither, and perish; but true Christianity should flourish and last for ever. And then, as a general inference from the whole of the sum of what he had said, he concludes (v. 31), So then, brethren, we are not children of the bond-woman, but of the free.
