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 (Gal 4:22, Gal 4:23): 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 (Gal 4:24-27): 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 (Gal 4:28); 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 (Gal 4:31), So then, brethren, we are not children of the bond-woman, but of the free.

For this Agar is Mount Sinai in Arabia - Το γαρ Αγαρ Σινα ορος εστιν εν τη Αραβια. This is the common reading; but it is read differently in some of the most respectable MSS., versions, and fathers; thus: το γαρ Σινα ορος εστιν εν τῃ Αραβια, for this Sinai is a mountain of Arabia; the word Αγαρ, Agar, being omitted. This reading is supported by CFG, some others, the Ethiopic, Armenian, Vulgate, and one copy of the Itala; by Epiphanius, Damascenus, Ambrosiaster, Jerome, Augustine, Hilary, Sedulius, and Bede; and the word is sometimes, though not always, omitted by Cyril and Origen, which proves that in their time there were doubts concerning the common reading.

Of the word Agar in this verse, which renders the passage very obscure and difficult, Professor White says, forsitan delendum, "probably it should be expunged." Griesbach has left it in the text with a note of doubtfulness.

Answereth to Jerusalem - Hagar, the bond maid, bringing forth children in a state of slavery, answereth to Jerusalem that now is, συστοιχει, points out, or, bears a similitude to, Jerusalem in her present state of subjection; which, with her children - her citizens, is not only in bondage to the Romans, but in a worse bondage to the law, to its oppressive ordinances, and to the heavy curse which it has pronounced against all those who do not keep them.

But Jerusalem which is above,.... This Sarah was a type and figure of; she answered to, and agreed with this; which is to be understood, not of the church triumphant in heaven, but of the Gospel church state under the administration of the new covenant; and that, not as in the latter day glory, when the new Jerusalem shall descend from God out of heaven, but as it then was in the apostle's time, and has been since. Particular respect may be had to the first Gospel church at Jerusalem, which consisted of persons born from above, was blessed with a Gospel spirit, which is a spirit of liberty, out of which the Gospel went into all the world, and from among whom the apostles and first preachers of the word went forth everywhere, and were the means of the conversion of multitudes, both among Jews and Gentiles, and so might be truly said to be the mother of us all. The church in general, under the Gospel, may be, as it often is, called Jerusalem, because of its name, the vision of peace; being under the government of the Prince of peace; the members of it are sons of peace, who are called to peace, and enjoy it; the Gospel is the Gospel of peace, and the ordinances of it are paths of peace; and the new covenant, under the administration of which the saints are, is a covenant of peace. Jerusalem was the object of God's choice, the palace of the great King, the place of divine worship, was compact together, and well fortified: the Gospel church state consists of persons, who, in general, are the elect of God, among whom the Lord dwells, as in his temple. Here his worship is observed, his word is preached, and his ordinances administered; saints laid on the foundation, Christ, and being fitly framed together, grow up unto an holy temple in him, and are surrounded by him, as Jerusalem was with mountains, and are kept by his power unto salvation. This is said to be above, to distinguish it from the earthly Jerusalem, the inhabitants of which were chiefly men of the world, carnal men; but this heavenly Jerusalem, or Gospel church state, chiefly consists of persons born from above, called with an heavenly calling, and who bear the image of the heavenly one, whose conversation is in heaven, who are seeking things above, and in a little time will be there themselves; its constitution and form of government are from above, and so are its doctrines, and its ordinances. The Jews often Speak of

, or or , "Jerusalem above" (x), as distinguished from Jerusalem below: and to this distinction the apostle seems to have respect here, who further says concerning this Jerusalem, that she

is free; from the servitude of sin, Satan, and the world, from the yoke of the law, and from a spirit of bondage; having the Spirit of God, the spirit of adoption, who is a free spirit, and makes such free that enjoy him; and where he is, there is true liberty. He adds,

which is the mother of us all; that are born again, whether Jews or Gentiles, as particularly the church at Jerusalem was, and the Gospel church state in general may be said to be; since here souls are born and brought forth to Christ, are nursed up at her side, and nourished with her breasts of consolation, the word and ordinances. This form of speech is also Jewish: thus it is said (y) that

"Zion, , "the mother of Israel", shall bring forth her sons, and Jerusalem shall receive the children of the captivity.''

Again, explaining Pro 28:24 it is observed (z), that there is no father but the ever blessed God, , "and no mother" but the congregation of Israel. Some copies leave out the word "all"; and so do the Vulgate Latin, Syriac, and Ethiopic versions, and only read, "the mother of us", or "our mother".

Translate, "For this word, Hagar, is (imports) Mount Sinai in Arabia (that is, among the Arabians--in the Arabian tongue)." So CHRYSOSTOM explains. Haraut, the traveller, says that to this day the Arabians call Sinai, "Hadschar," that is, Hagar, meaning a rock or stone. Hagar twice fled into the desert of Arabia (Gen. 16:1-16; Gen 21:9-21): from her the mountain and city took its name, and the people were called Hagarenes. Sinai, with its rugged rocks, far removed from the promised land, was well suited to represent the law which inspires with terror, and the spirit of bondage.

answereth--literally, "stands in the same rank with"; "she corresponds to."

Jerusalem which now is--that is, the Jerusalem of the Jews, having only a present temporary existence, in contrast with the spiritual Jerusalem of the Gospel, which in germ, under the form of the promise, existed ages before, and shall be for ever in ages to come.

and--The oldest manuscripts read, "For she is in bondage." As Hagar was in bondage to her mistress, so Jerusalem that now is, is in bondage to the law, and also to the Romans: her civil state thus being in accordance with her spiritual state [BENGEL].
